Please help me with my gcse music homework!! Here is the question I've been given;
How much time, in crotchet beats, does a crotchet triplet take up?
A triplet figure is assumed to have a 2:3 ratio of metric duration to notated duration under the triplet.
Remember that you can derive many of these rhythmic rules yourself by examining real music. A measure of 2/4 time, for example, will always contain a full half note of rhythmic duration: never more, never less. If a measure of printed music contains three eighth notes under a triplet plus two more eighth notes, you can set up a little rhythmic algebraic equation as follows:
3<triplet eighth> + 2eighth = half
Then solve for
<triplet eighth>! A
half = 4eighth, so if you subtract out the
2eighth from each side, you get:
3<triplet eighth> = 2eighth
Then divide each side by 3:
<triplet eighth> = (2/3)eighth
Who says algebra isn't useful for musicians? :-)
