  • We can, of course, divide our rhythms into subdivisions of three, five, seven, etc.

  • These are generally referred to as tuplets and

  • can be any arbitrary division of a note, but the most common are in fact triplets.

  • There are as you might imagine,

  • three triplets quavers, or eighth notes to a quarter note, three in the time of two.

  • Or three triplet quarter notes to a half note.

  • Any basic rhythm could be subdivided in this manner.

  • So if I've got a beat that goes at this speed,

  • [NOISE] that would be quarter notes.

  • And triplets would be [NOISE] one, two, three.

  • One, two three.

  • One, two, three.

  • One, two, three. One, two, three.

  • One, two, three.

  • As mentioned, we can have other subdivisions, for instances, quintuplets.

  • So for example, I could divide a minim, or a half note,

  • into five quintuplet eighth notes.

  • That would go something like this.

  • [NOISE] One, two, three, four, five.

  • One, two, three, four, five.

  • One, two, three, four, five.

  • One, two, three, four, five.

  • Tuplets are generally notated in the simplest fashion by putting a number above

  • a beam, as in the triplet quaver or eighth notes we've already seen.

  • The three there implicitly means three in the time of two.

  • So whereas a crotchet, or a quarter note, would usually be divided into two quavers,

  • or eighth notes.

  • By putting the three above three quavers,

  • we indicate that we want these three triplet eighths to be in the time of two.

  • We can also use brackets with numbers if we have notes that we don't have flags or

  • beams for.

  • So to create triplet quarter notes, we would normally use the bracket to group

  • the three notes that we want played in the time of two.

  • And if it's not obvious how many shorter notes we want in the time of how many

  • longer notes, we could explicitly write a proportion such as 4:3.

  • [MUSIC]

We can, of course, divide our rhythms into subdivisions of three, five, seven, etc.
