There's a discussion buried somewhere about LEFT HAND SLAP(ie, 'the fretting hand')- ...I usually post a Dave Larue link to a lesson from Bass Player mag(I'm not sure BP's site still has it, though they might...I'll check later when I have more time). Getting both hands working together/against each other would be a start. Learning the Clave & other assorted polyrhythmic figures would help(you can practice this without the bass in yer hands...you assign one rhythm to one hand & the other rhythm to the other hand; drummers & pianists do this all the time). The concept is to produce counter or cross-rhythms...that's my .02 for now.
Im not very familiar with this double hand/ percussive slapping. Or, maybe I am and dont know it. Can you recommend any tunes that use it?
Here's the links(assuming they're still there)- Left-Hand Slap http://www.bassplayer.com/z1998/9809/larue.shtml Slapping Across The Bar Line http://www.bassplayer.com/z1998/9812/larue.shtml Slapping In Groups Of Five- http://www.bassplayer.com/z1998/9810/larue.shtml ...don't forget about Wooten's "Open Hammer Pluck" & the 'flam' technique(both are at Wooten's site). I always mention learning the Clave(s) by tapping them out with both hands(on a desk, on yer gal's head, etc). Once that becomes familiar, you can transfer that bit of knowledge to the bass...something I'm still trying to absorb. Later.
