  • Prof: Okay. Good morning.

  • Over the weekend, you were assigned material from

  • chapter one of the text and it dealt really with three famous

  • beginnings of pieces of classical music.

  • Somebody tell me at the outset: what were those three famous

  • pieces?

  • Young lady down here.

  • Student: The first was Beethoven's.

  • Prof: Okay, Beethoven's Fifth Symphony.

  • What was the second one?

  • Student: I believe it was Tchaikovsky's Piano Concerto

  • Number One.

  • Prof: Yeah, Piano Concerto Number One of

  • Tchaikovsky, and the third one?

  • Student: >

  • Prof: Yeah, this piece by Richard Strauss

  • with this funny sounding German name.

  • We'll just call it Zarathustra, this

  • prophet, Zarathustra.

  • So those are the three pieces and the issues there had to do

  • with musical genre that we're going to talk a little bit more

  • about in a moment, and the instruments.

  • And you went ahead and worked with the Listening Exercises

  • nine through eleven to engage the musical instruments a bit in

  • those particular exercises, and we have performers here

  • today that are going to, as you can see,

  • demonstrate some of these instruments for us.

  • Let's make one point very clear at the outset.

  • Oftentimes I get student papers that refer to "Beethoven's

  • fifth song" or "Tchaikovsky's first

  • piano song."

  • Is that right?

  • No, that's not good at all.

  • Are these songs?

  • What do you have to have to make something a song?

  • Student: Lyrics.

  • Prof: Lyrics.

  • You've got to have a text and so we don't have--in eighty

  • percent of classical music--we don't have lyrics;

  • we don't have a text.

  • Well, yes, with opera of course, but the other eighty

  • percent is purely instrumental music.

  • It works its magic, again, through purely

  • instrumental means, so we can't really call those

  • songs, and this puzzled me.

  • One day I was sitting there at iTunes and I wanted to buy an

  • interior movement of a Mozart serenade so I was all set to

  • purchase this and it said, "Buy song."

  • Boom.

  • That told me the answer.

  • That's where this terminology comes in to play because on

  • iTunes we buy songs.

  • It could be purely instrumental but it's called "buy a

  • song," but we don't want to use that sort of parlance.

  • We want to be more--a bit more sophisticated than that,

  • if you will, and use other terms,

  • so we'll talk generally about Beethoven's composition or

  • Beethoven's piece or Beethoven's work or his master work or

  • chef d'oeuvre or however fancy you want to get with it.

  • We could also go on and be a little more precise and say it

  • belongs to a particular genre.

  • We could use the name of a genre, and I'll be talking a lot

  • about genre in this course.

  • "Genre" is simply a fancy word for

  • "type" or "kind"

  • so what genre of piece is this by Beethoven?

  • Well, it's a symphony.

  • Symphonies generally have four movements.

  • What's a movement?

  • Well, a movement is simply an independent piece that works

  • oftentimes-- if there are multiple movements

  • in a symphony or concerto-- works with other movements.

  • They are independent yet they are complementary.

  • Think of, for example, a sculpture garden.

  • You might have four independent sculptures in there,

  • but they relate one to another; they make some sort of special

  • sense one to another.

  • So symphonies have these four movements and they usually

  • operate in the following way: A fast opening movement;

  • a slower, more lyrical second movement;

  • then a third movement that's derived from dance;

  • and then a fourth movement that's sort of again "up

  • tempo," fast, emphatic conclusion.

  • Let's see how these play out by means of a quick review of

  • Beethoven's Fifth Symphony so all we're going to do here is

  • going to go from the beginning of the track for the first

  • movement to the second movement and so on,

  • and well, let's just start here.

  • Let's just, by way of refreshing our memory,

  • the beginning of Beethoven's Fifth Symphony.

  • >

  • Let's pause it there, and as we said last time,

  • it operates <<music playing>>

  • in that fashion, and that beginning gives us a

  • good opportunity to make a distinction between two types of

  • melody, between this idea of a motive

  • and a theme.

  • Both are sort of subsets of melody, if you will.

  • As I say in the textbook there, the beginning of the Beethoven

  • Fifth is something like a musical punch in the nose.

  • Right?

  • >

  • Sort of grabbing you here, hitting you in the face,

  • whatever, musically.

  • It's not a very long idea.

  • How many notes is in this opening gambit here?

  • How many pitches?

  • Four, >

  • short, short, short, long.

  • Okay.

  • So that's a classic example of a motive.

  • A motive is just a little cell, a germ, out of which the

  • composer will build other musical material.

  • Now let's contrast that with what happens in the second

  • movement of Beethoven's Fifth Symphony where we have a

  • lyrical, long, flowing theme.

  • Okay?

  • >

  • Okay. We'll stop there.

  • All right?

  • So that went on--If we heard the whole thing,

  • it actually goes on for 32 notes as opposed to just four so

  • motive versus longer theme.

  • Themes tend maybe a little bit more lyrical.

  • Now let's go on to the third movement.

  • We said the third movement was dance derived,

  • but in this case with Beethoven it's a very strange dance if it

  • is dance derived.

  • It's just a little bit different than most of these

  • third movements, but let's listen to it anyway

  • because I'd like you to-- when the brasses come in--think

  • about what you're hearing and think about that

  • vis-à-vis the first movement,

  • so let's hear the third movement now.

  • >

  • Okay.

  • So what happened there when the brasses came in?

  • How did that relate to the first movement?

  • Yes? Student: Four notes?

  • Prof: Four notes, something as simple as that,

  • >

  • , same rhythmic idea, so that's the use of a motive

  • there and that's how these movements are tied together a

  • little bit.

  • Let's go on to the finale now, and as we listen to the finale

  • let's think about what we heard at the very beginning and talked

  • about last time, >

  • about the mood that the beginning of the Fifth Symphony

  • created for it.

  • We have these adjectives up here, "negative,"

  • "anxious," "unsettled."

  • Well, how do we feel now about the finale and why?

  • >

  • So why do we feel differently about that?

  • I think we do.

  • What do we feel there?

  • Well, sort of upbeat, positive.

  • What's turned all of this around, what specifically?

  • Well, with the first movement we said he's generally going

  • >

  • and that kind of idea, but now it's <<music

  • playing>>

  • and we'll explore this when we get to harmony,

  • this idea of major and minor so we're going <<music

  • playing>>

  • and now <<music playing>>

  • and that's a change from the dark minor to the brighter

  • major.

  • We were going down in the first movement.

  • Now we're going-- <<music playing>>

  • It's going up and instead of having just the violins playing

  • we have the trumpets, the heroic trumpets,

  • so it sounds very triumphant.

  • So in this 40-minute interval we've gone sort of through an

  • emotional musical journey here from despair,

  • despondency, uncertainty,

  • to whatever- to personal triumph,

  • and in a way that mirrors some of the things that were going on

  • in Beethoven's life.

  • Okay.

  • Let's go on to talk about the second piece.

  • We finished with this idea of the genre, of the four

  • movements, so then let's go on to talk about the piano

  • concerto.

  • Concertos are generally in three movements.

  • The concerto is another genre.

  • It's a genre in which a soloist will confront the orchestra and

  • there'll be a kind of give and take--a spirited give and

  • take--between the two.

  • So now we are going to listen to the beginning of the first

  • movement of Tchaikovsky's Piano Concerto.

  • You've worked with this already so you're a little bit familiar

  • with it, and at the outset here I have two questions for you.

  • Is the beginning here played by the brasses or the strings?

  • In other words, what--or the woodwinds--

  • what family of instruments is playing here and is Tchaikovsky

  • using a motive or is he using a theme at the very beginning of

  • this concerto?

  • >

  • So what about that?

  • Theme or motive at the beginning?

  • Student: Motive.

  • Prof: Motive. All right.

  • So here it was I think.

  • >

  • How many notes in our motive?

  • >

  • Same as in the Beethoven.

  • Why isn't it the same?

  • Well, we've got a skippy Beethoven <<music

  • playing>>

  • but here with Tchaikovsky he's coming down, just straight down,

  • >

  • down consecutive intervals there for the most part.

  • And both of them are, however, minor.

  • >

  • With the Tchaikovsky they--all the intervals are the--the

  • durations are the same, >

  • but with the Beethoven, >

  • short, short, short, long.

  • So Tchaikovsky is a little bit more neutral in terms of the

  • rhythm.

  • Okay.

  • So then we go on and the piano enters.

  • What is the piano doing?

  • So let's hear the piano come in just a bit.

  • >

  • So what's the piano up to?

  • Well, the piano is just playing chords, <<music

  • playing>>

  • playing them in octave successions, and we'll talk

  • about that a little bit more too.

  • So what do we have here in this next section?

  • Do we have a theme or do we have a motive and which do

  • this--are the violins playing?

  • Are they--Do they have the theme or the motive or does the

  • piano have the theme or the motive?

  • Let's listen.

  • >

  • So was--what the--what were the violins playing?

  • Theme or motive?

  • Theme. What was the piano doing?

  • Student: *.

  • Prof: Yeah, just the same chords

  • >

  • >

  • in that fashion.

  • I'm singing the melody.

  • They're playing a chordal accompaniment against it.

  • All right.

  • Let's listen to the next iteration of this theme.

  • We've identified this as a theme.

  • Who's got the theme now?

  • Is it exactly the same?

  • And what are the strings up to in terms of string technique

  • here?

  • >

  • So who had the theme?

  • The piano now, but was it exactly the same?

  • Not really.

  • It was kind of noodling around with it, varying it a little

  • bit.

  • What were the strings doing?

  • They were playing the accompaniment,

  • and what string technique were they using?

  • I think we mentioned that in the first chapter of the book

  • there.

  • Yeah, you've got it.

  • Nice and loud please?

  • Student: Pizzicato..

  • Prof: Pizzicato.

  • Good.

  • Okay, pizzicato.

  • We could write that--Did we write that as a term up--Yeah.

  • Okay.

  • We've got it up there, pizzicato.

  • That's a help.

  • So in that particular case we've switched the roles around.

  • We're going to move this along just a little bit here.

  • As we come back in to this, I think we've got a situation

  • where the piano keeps playing the four-note motive,

  • >

  • the part like he was building it up for tension.

  • Then there's a cascade and then the theme comes back.

  • Let's see what happens here, >

  • just the motif, one, two, three,

  • four, three four, one two, <<music

  • playing>>

  • and then the theme.

  • >

  • The piano is playing >

  • , ornamenting.

  • All right.

  • So that's an introduction to a three-movement piano concerto.

  • It happens to be the first of these three movements and it's

  • pretty spectacular music.

  • I hope you like that music.

  • It's one of the great melodies of all time.

  • It's a wonderful example of a theme.

  • Having talked just a little bit about genres,

  • we could conclude by saying there are other kinds of genres

  • in music of course.

  • We've been introduced to this idea of the tone poem.

  • The Strauss Zarathustra is a tone poem.

  • That's a one-movement work in which the composer tries to tell

  • a story or play out an historic event or,

  • in the case of the Strauss, to give us the beginning of the

  • contents of a philosophical novel through music.

  • So tone poems are one in movement, and we have got other

  • kinds of genres in music.

  • We've got opera.

  • We've got cantatas, sonatas, ballets,

  • things such as this, and we'll get to each of those

  • in turn.

  • So that's the end of the discussion of genre.

  • Let's go on now to talk about instruments and how instruments

  • produce sound.

  • Eva Heater, come on up.

  • This is my friend, long-time colleague,

  • music librarian extraordinaire and professional French horn

  • player, Eva Heater, who will

  • demonstrate here-- Come on over here right in the

  • center.

  • Gene Kimball is in the basement somewhere recording all of this.

  • Eva Heater: Oh, my..

  • Prof: Oh, yeah.

  • It's very exciting here.

  • What a time to be alive, huh?

  • Eva Heater: Yeah.

  • Prof: So Eva is going to just demonstrate the physical

  • process of playing the French horn.

  • Eva Heater: The horn obviously is a

  • brass instrument and what makes the sound is a vibrating column

  • of air.

  • In this case, the basic column of air is

  • twelve and a half feet long and there are something called

  • "partials" or the "harmonic

  • series" that happens in anything,

  • on a string instrument or whatever,

  • but on the horn it's very distinct and that's what makes

  • the different notes.

  • Let me demonstrate to you the harmonic series.

  • >

  • Now I didn't use--no hands--that was just the notes

  • that are naturally on the twelve and a half-foot length of

  • vibrating air.

  • That's the harmonic series that's on that,

  • and what the valves do is they shorten and lengthen that

  • vibrating column of air very much like the cello string on

  • the fingerboard.

  • A cellist is always shortening and lengthening the strings.

  • I'm doing the same thing.

  • I'm just doing it with a series of switches instead of a

  • fingerboard, which we obviously don't have--

  • Prof: Okay.

  • That's fine.

  • That's great.

  • That's the principle, and when she said she was

  • "overblowing" what that means is,

  • and we'll keep emphasizing this point today--

  • these partials--that when a sound is made you have not just

  • one sound but that tube is dividing up into sections,

  • and all kinds of little sections of that one tube are

  • sounding, not just the big sound but the

  • partials or the overtones, the intervals in the harmonic

  • series.

  • So it's a whole series--when we listen to a single tone it's a

  • whole series, and what Eva was doing there is

  • playing out the notes in that series successively,

  • and we'll keep banging on that.

  • Now if you would, Eva, play just the beginning of

  • the Zarathustra or the trumpet part.

  • Can you do that?

  • >

  • Go, Eva. Go.

  • >

  • One more time.

  • >

  • Okay, and that's another note.

  • Thank you very much.

  • Thank you. Thank you.

  • Okay.

  • Now Eva has another gig out in Gilford this morning so she's

  • going to run off, and I'm going to show you,

  • maybe, if we can get our slides up,

  • this overtone series stuff.

  • Okay?

  • Eva Heater: Okay.

  • It's a mathematical thing too.

  • It's all math.

  • Prof: What we've got here is the following,

  • this idea of partials that Eva was talking about with ratios,

  • two to one, three to two, four to three,

  • five to four, six to five and so on,

  • and the point here is that the way we differentiate between

  • instruments.

  • Can anybody tell me this, why--You tell me this.

  • It's always better when students answer.

  • Why does a trumpet--If I asked a trumpet to play this pitch,

  • a trumpet played, and then I asked an oboe to

  • play it, the sound would be very different.

  • Why is that the case?

  • Gentleman here?

  • Student: Different overtones?

  • Prof: Different overtones.

  • Well, actually they all have the same overtones in a way,

  • the same frequencies will sound, but you've got

  • it--ninety-nine percent of it.

  • It's which partials are particularly prominent,

  • have extra punch or extra volume to them.

  • The oboe may have the seventh partial very strong and the

  • third partial very strong whereas the trumpet--

  • I'm just making all of this up of course--

  • the trumpet may have the second partial and the fourth partial

  • and the sixth partial.

  • So it's which of these partials are sounding within each of

  • these instruments, and the physical properties of

  • each of these instruments are different.

  • It's the particular blend.

  • Here's a really dumb analogy.

  • Any Scotch drinkers in here?

  • No, of course not.

  • You're way too young to do that, but think about a blended

  • Scotch.

  • You've got a little of this, a little of this,

  • a little of this, and it makes up whatever it is

  • that you end up with, the particular recipe for that

  • liquid.

  • Well, we have a particular recipe for instrumental timbre

  • or instrumental color and it's the intensity of the overtones

  • with-- or partials--within each

  • particular instrument that creates that.

  • Okay.

  • Now we're going to go on and talk about a woodwind instrument

  • here so Lynda, come on up.

  • Lynda is a bassoonist.

  • This is Lynda Paul who will be one of our principal TAs here.

  • She is a PhD candidate in the department of music,

  • just passed her qualifying exam with flying colors,

  • so here she is to demonstrate the bassoon for us,

  • lowest member of the woodwind family.

  • Lynda Paul: All right.

  • So you probably read in the book that the bassoon is a

  • double reed instrument, and so just to show you what

  • that looks like-- You've probably seen it but if

  • you haven't, two pieces of wood vibrate

  • together when I blow through them.

  • >

  • I always check it out before I play any notes.

  • And, as you will probably suspect, by the length of the

  • bassoon it can play very low notes <<music

  • playing>>

  • and if I put a little rag in the top I can get it even a

  • little bit lower than that-- I didn't bring one--but

  • actually, amazingly, it's a very versatile

  • instrument and can also play very high notes.

  • As you can see, there are a lot of keys in it.

  • There are nine keys for my left thumb alone so I'm kind of

  • switching between these on the back here and many others,

  • and because of that I can go very high and I'll just

  • demonstrate that.

  • >

  • So that's just to give you a sense of the range.

  • Because of the sort of particular character of the

  • bassoon sound, it's often used to play sort of

  • funny, little low-note characters in the orchestra.

  • For example, if you're familiar with

  • Peter and the Wolf, the different instruments play

  • different characters.

  • The bassoon is the grandfather.

  • >

  • Prof: Cool. Okay. Great.

  • Thanks so much.

  • That--That's really fun.

  • Now Jacob Adams is a professional violist here in New

  • Haven.

  • What's the name of your quartet, Jacob?

  • Jacob Adams: I'm a member of the

  • "Vinca String Quartet."

  • Prof: The "Vinca String Quartet"

  • so keep an eye out for them.

  • They're based here in New Haven.

  • So come on out, Jacob.

  • And he is a violist, not a violinist,

  • but the principle here is pretty much the same,

  • so tell us about the construction of the instrument.

  • Jacob Adams: Okay.

  • So obviously we've now seen a little bit of the brass family

  • and the woodwind family, and the other principal section

  • of the orchestra would obviously be the string family.

  • The viola is very similar to the violin so anything I say

  • about the viola applies to the violin as well,

  • and of course you all are probably familiar with violins

  • and the size.

  • The violas are a little bit bigger.

  • This particular one is about 16 inches long.

  • Violins are--maybe--go up about to twelve inches.

  • They have a slightly smaller body to them but violins and

  • violas have the same general construction.

  • All of the sounds are produced by the strings on the instrument

  • and how the bow is pulled across the instrument.

  • The bow is made out of, typically, horse hair from the

  • tails of horses.

  • The strings are now metallic but sixteenth,

  • seventeenth to eighteenth century they would have been

  • made out of cat or sheep gut.

  • That was much more common, and still some people--

  • Prof: Okay. So I'm sorry.

  • We've got lots of things going on here this morning so just

  • play a scale quickly and then vibrato, pizzicato and tremolo

  • for us.

  • Jacob Adams: So again this is on a viola

  • so it has a deeper, darker timbre than a violin but

  • here's a scale.

  • >

  • Prof: Wow.

  • You did something there at the end.

  • Did you have too much coffee this morning?

  • You started shaking over there.

  • Yeah.

  • So tell us about what you were doing there at the end.

  • Jacob Adams: So there are all sorts of

  • different little technique things you can do to create

  • different colors and sounds on all string instruments,

  • so this applies to any of them.

  • One of them is the technique you saw me do with my left hand

  • where I wiggled it a little bit.

  • It's called vibrato.

  • You hear it in human voices as well.

  • You can do it on other instruments but on a string

  • instrument it's the difference.

  • I'll play a melody without vibrato and with vibrato so you

  • can see the difference.

  • >

  • So that's without vibrato, not that interesting in my

  • opinion, so with vibrato.

  • >

  • And you can vary the width and the speed and the length.

  • There's a lot of varieties which--

  • Prof: Okay.

  • And then just quickly play a pizzicato for us?

  • Jacob Adams: Sure.

  • >

  • Prof: Okay, and then finally tremolo.

  • Jacob Adams: Tremolo,

  • yes.

  • >

  • Prof: So adds a little excitement or a little filler to

  • the music sometimes.

  • Jacob Adams: Uh huh..

  • Prof: All right.

  • Great.

  • Thank you, Jacob, very much.

  • What I wanted to show you was a clip that actually my daughter

  • brought to my attention just this past weekend.

  • She was watching television, "America Has Talent."

  • Does anybody watch this, "America Has Talent"?

  • And she said, "Dad, you've got to watch

  • this.

  • This is the most amazing thing.

  • They've got these two guys on here called Nuttin' But

  • Strings."

  • So I did.

  • I--And I went to--She sent me the link to YouTube here.

  • >

  • All right.

  • So obviously the violin is not just this stodgy old thing from

  • the Renaissance.

  • It has some legs today, used in folk music.

  • Sometimes you see it in Nashville playing with country

  • music, that kind of thing.

  • Is this a travesty to use a violin with hip-hop here?

  • I guess this is hip-hop.

  • Of course not.

  • This is wonderful.

  • This is the best thing that has happened to the violin in the

  • last hundred years.

  • There will be millions of kids out there now that say

  • "Gee, I'd like to learn to play the violin too."

  • So this is wonderful, this sort of cross-semination

  • of genres here, bringing this particular

  • instrument, the traditional classical

  • violin, into the popular realm.

  • All right.

  • So let's put that aside.

  • We've talked a little bit about sound production here.

  • I've got two pieces I'm going to work with here for the end of

  • our session.

  • We have 15 minutes left and here are these two pieces.

  • The first, you can see on the board up there,

  • is by another Russian composer, Modest Musorgsky.

  • It's called "Polish Oxcart" from his work

  • Pictures at an Exhibition.

  • What happened was he had a friend.

  • The friend died.

  • The friend was an artist.

  • The friend left these pictures as an homage to the

  • painter.

  • Mussorgsky sat down and tried to come up with,

  • create a musical response to each of these paintings that

  • were on display.

  • Now this is a piece that's always interested me because the

  • painting is very pedestrian.

  • It's of an old Polish oxcart sitting on some godforsaken road

  • in rural Russia somewhere.

  • So how do you make that work as music?

  • How do you turn that visual image into music?

  • How do you turn that into a sort of live sonic-scape?

  • And I should say at the outset--I'm going to prejudice

  • your listening here just a little bit.

  • I hear this as me being in the center and this oxcart

  • starting--It could start at either side.

  • It doesn't matter.

  • Every written thing usually moves left to right so I'm going

  • to hear this moving left to right.

  • It comes in front of me, almost rolls over top of me,

  • runs me down, and then disappears to my

  • right, so as we listen to this,

  • you think about what are the techniques by which Musorgsky

  • creates this musical action scene.

  • You should be able to come up with two pretty good ideas here,

  • two pretty good answers.

  • All right. Here we go.

  • >

  • Now the instrument is--that is--playing is a low tuba,

  • a low brass instrument.

  • It doesn't sound much like a tuba because it's actually

  • playing in the higher register of the instrument,

  • but it is a tuba.

  • >

  • Okay. Now the strings.

  • The strings come in with a counter-idea,

  • a complementary idea.

  • >

  • Okay.

  • Give me one pretty straightforward way this

  • happened.

  • What did he do there?

  • Yes, young lady out here please.

  • Student: Crescendo?

  • Prof: Okay, crescendo.

  • From beginning to end?

  • Student: Got louder, then softer.

  • Prof: Yeah, so like a giant wedge,

  • that's why the cart seems to move in front of you,

  • so we're talking about musical volume here.

  • It started very quietly, it built up to this huge center

  • in which we had the bass drum pounding away there and the

  • snare drum coming in to give the effect that the entire earth is

  • rattling at that particular point,

  • and then as it passed by you--the thunder passed by you--

  • and off it went into the distance, quietly into the

  • distance.

  • We'll come back to that, but how did that happen?

  • We'll listen to the end of that in just one moment.

  • It's kind of a disintegration of the sound at the end.

  • So that's one big way this happened.

  • That's probably the big-ticket item here.

  • There's another way, a more subtle way.

  • Any thoughts about that?

  • Yes?

  • Student: The instrumentation?

  • Prof: Yes, the instrumentation.

  • Can you elaborate on that?

  • Student: Yeah.

  • It starts with low instruments and then moves to higher ones,

  • and then back to low ones.

  • Prof: Great. Right.

  • So there's a kind of wedge shape with regard to the

  • instruments too.

  • He started with the lowest instruments and then goes to the

  • high instruments and then back to low instruments at the end.

  • Let's just review--Well, no, we won't review this.

  • Let's not review that. Okay?

  • We don't have time to review that, but let's go on to say the

  • following, that what Musorgsky knew there

  • was a very basic principle of acoustics,

  • and what is that principle?

  • Yeah?

  • Student: Doppler principle..

  • Prof: I beg your pardon?

  • Student: Doppler principle.

  • Prof: Well, to some extent.

  • I'm going to give an example or--example of that--of the

  • train kind of going by you, and the sound heading off in

  • the other direction.

  • Yes, to some extent it is that, yes,

  • but what I was thinking about here is this idea that the

  • lowest sounds create the longest sound waves,

  • and they last the longest.

  • The lowest sounds create the largest sound waves and they

  • last the longest.

  • The lowest sounds last the longest.

  • Why might this be the case?

  • If we're not having too much luck with our slides this

  • morning, I went ahead and put this one up on the board here.

  • Here is one pitch.

  • Here is the pitch in--of--a string an octave higher so you

  • can see it this way.

  • As you probably know, if you take a long string and

  • pluck it, it's going to take that long

  • string a long time to pass that sort of cycle,

  • if you will, just one pass through that

  • cycle.

  • The string half a length will pass through that cycle two

  • times so that you can kind of graph these up here as one long,

  • low sound or one faster vibrating sound an octave

  • higher, so again low sounds or low

  • frequencies travel farther.

  • Now you've experienced this in your own life.

  • You're standing on a street corner here in New Haven.

  • In the distance what do you hear?

  • An automobile approaching with a souped-up audio system in it,

  • and what sound do you hear at the very first?

  • >

  • That kind of thing.

  • Then maybe <<d- d- d- d- d>>

  • and then maybe some kind of melody will come in and then

  • it'll all come together right in front of you and it'll kind of

  • disappear in the distance.

  • You're at a football game.

  • You've probably experienced this too.

  • The band is marching on the field.

  • Suddenly they do the Doppler effect where they turn their

  • backs to you, in a way, and they're marching

  • away from you and you hear very little sound.

  • What instrumental sound do you hear?

  • >

  • The bass drum and the tuba or in the marching band it would be

  • a sousaphone they would call it, the bass drum and tuba.

  • So Musorgsky knew this law of acoustics because he was a

  • professional musician and was playing off of it to create this

  • rather unusual and remarkable musical sound-scape here.

  • Okay. I have five minutes left.

  • I'd like to do one last piece.

  • It's another piece by Richard Strauss.

  • It kind of brings us to the end of Richard Strauss,

  • our discussion of Richard Strauss.

  • We'll say good-bye to him here in our course.

  • It's called Death and Transfiguration,

  • and I hear this as a companion piece, a kind of pendant to the

  • Zarathustra.

  • One sort of opens up the beginning of life here and the

  • other closes it down through a referencing of death.

  • There's an interesting anecdote about Strauss,

  • and that is that on his deathbed he said to his

  • daughter, Alice--He said, "Alice,

  • it's the funniest thing.

  • Dying is exactly as I composed it in Death and

  • Transfiguration."

  • What an odd thing to say, but in any event

  • >

  • here is how this works.

  • We've been talking about this overtone series with

  • Zarathustra.

  • Eva played this overtone series.

  • He's basically working up to the upper partials.

  • Now he's going to work down the partials.

  • He's going to close it back down here with death and he's

  • going to close it back down using a process that we

  • frequently encounter in music, and that is this idea of

  • dissonance resolving to consonance.

  • Here is a dissonance.

  • >

  • Here is a consonance.

  • >

  • There are precise technical reasons why these are the way

  • they are, but let me try to cut to the chase here.

  • With dissonant intervals they tend to be frequencies that are

  • sounding right next to each other, very close-by

  • frequencies.

  • They sound dissonant.

  • If you allow a little bit of spacing,

  • a little more space between your frequencies,

  • they're a little bit farther apart,

  • then you can move from closeness <<plays

  • chord>>

  • to >

  • spacing and you get the consonance.

  • Generally speaking, dissonant intervals have ratios

  • such as nine to eight for the whole step or seventeen to

  • sixteen for the half step.

  • They're irrational numbers and these irrational numbers like to

  • move to rational numbers; they like to move to

  • consonances; they like to move to intervals

  • that are based on things such as two to one and three to two or

  • maybe four to three.

  • So that's the principle of this idea of dissonance resolving to

  • consonance.

  • So we're going to listen now to the end of Strauss's Death

  • and Transfiguration, and again we've got the idea of

  • the octave, then the fifth, then the fourth.

  • We're working up farther and farther in these partials and

  • we've got some of these notes right next to each other and

  • they want to move to the stable notes so we're going to be

  • hearing a lot of a note right above the tonic wanting to pull

  • down to that tonic note.

  • We're going to hear a lot of the note right above the

  • dominant wanting to pull down to the dominant.

  • So let's listen to this.

  • We have about three minutes I think.

  • We'll hear it and I'll comment a bit as we go.

  • >

  • Okay.

  • First question: What string technique is being

  • used here?

  • Tremolo.

  • Just sawing away there.

  • >

  • Now just working with the four-note motive here--

  • >

  • Whoah.

  • A strange little dissonant chord there resolving to

  • consonance.

  • >

  • >

  • And here it's all just tonic, just the basic primordial note

  • upon which all these other tones are built.

  • >

  • Okay.

  • So that's Richard Strauss's approach to death,

  • not particularly relevant to you young people but for older

  • gentlemen such as Professor Kagan and myself we're getting

  • close to that.

  • Right, Don?

  • >

  • So thank you all for staying with this this morning.

  • I hope you enjoyed that music.

  • We'll see you in section starting this Thursday.

  • If you have any questions, come up and see me or send me

  • an e-mail.

Prof: Okay. Good morning.
