Lots of info out there about what to play melodically/harmonically (e.g. where to put a mixolydian in blues, what notes to play over a Bbmaj7#5, higher triads, quartal voicings, you name it.) Videos, books, etc. But so little attention seems to be paid to the same type of thing from the rhythmic side. I'd love to see some videos, for instance, where the instructor guitarist plays some great phrase and then explains what he did rhythmically. "This lick started on the upbeat before 3 and featured a run of 16th notes against the shuffle background beat....like so..." and then go on and demonstrate it again. Or " here I play just simple eighth notes, but I place them slightly behind the beat, like so..." I know there are drumming books for such, and sight reading texts that introduce you to all sorts of rhythmic patterns so that you can gain facility with playing them off the page. But, dammit, a lot of us just aren't ever going to sight read, and we need to build up our rhythmic vocab too. I think it's not done as much because rhythms are more easily captured just by listening and parroting back. My contention is that this is not enough, and that formalized instruction in rhythmic motifs could be really helpful to non-sight readers in expanding their musicality, improvisational sophistications, ability to nail the authenticity of a particular style of music, etc. Anyone know of any good sources?
