How do I rewrite music using a new time signature?
In Grade 5 Theory you might be asked to rewrite a short excerpt using a different time signature without changing the rhythmic effect. This is easy if both the old and new time signatures are simple time. Notice how the note values change when 3/4 becomes 3/8: Each note value is halved; for example, a minim becomes a crotchet and a dotted minim becomes a dotted crotchet. The task is more complicated when you are moving from simple time to compound time or vice versa. The first step is to look at the two time signatures and remind yourself what kind of beat and how many beats each signature represents.
