Hi Mike, thanks for the welcome. I've taken the drums up for fun, but it's really struck me how everything ties in rhythmically - ghost notes on the snare, syncopated LH comping for instance - yeah, Herbie has an incredible sense of rhythm. Having transcribed a lot of his music from the 70's, I can see what a genius he is when it comes to using rhythm and time signatures - not many people would guess from listening that Chameleon has 7/8 bars in the bridge, or that Sly has an 11/8 bar, or that Heartbeat has bars in 5/4, 7/8, 9/8 ...It's all about feel - I hate obscure time signatures when they're used in an ostentatious way for effect, but the changes in Herbie's compositions are so natural in feel that you can't fail to be blown away.
