X, what does compound time mean?
I read that today:
A time signature is compound if the top number is greater than three and can be divided by three.
Correct-- the bottom number will be 8, and the top number is divisible by three, and the primary felt and counted pulse will be a dotted quarter note, which is three 8th notes long, and creating a three note subdivision. That's what 6/8 is, that's why it's counted in 2.
For those Stone exercises-- you'll play that triplet-feel rhythm for the whole measure on the open and closed 7 stroke roll exercises-- just play multiple bounce strokes on the closed rolls, and double strokes on the open.
On the 9 stroke rolls, you'll be fitting four notes in the space of beat 2-- in effect, if we were in 2/4, it would be like playing an 8th triplet on 1, and 16th notes on 2-- with the double strokes or multiple bounce strokes to make the roll.
For the single stroke rolls, play the same rhythm as the open rolls, but with alternating singles-- equivalent to a sixtuplet or eight 32nd notes if we were in 2/4. It's very simple and easy to make the equivalency with 2/4 when you count in 2, and completely ridiculous (especially the 9s) and impossible to do at the correct speed if you count in 6.
exactly...but the operative word there is felt...felt in 2...should, and can still be counted in 6...neither way is wrong..and I teach the concept of compound to the kids later on, but only after they understand that 6/8 means 6 beats per measure, and the 8th note gets the beat <-- that is the foundational definition of the time signature.
I feel like if my kids understand the subdivision first, then later on, they can figure out rhythms in that time sig - or any - that don't have the "common feel"...I don't like my kids to learn by feel first, depending on the material. They learn to have feel...feel that is generated by clear understanding of how pulse and subdivision relate to each other
