Re: Videos: Max Roach
I'm wondering if it's truly like a tympani where you set the pitch and it stays until you change it again, or is it spring loaded so it always returns to the base pitch unless you pushing on the pedal. That's what it looks like to me, since he never really holds it on one pitch, it's always wavering and sliding the pitch up or down, and the drum always returns to the same place when he's not doing the slidey-pitch change thing.
Another technique that Art Blakey used to get the same effect was to use flexible tubing in the vent holes of the drums. By putting the opposite end of the tubing in his mouth and blowing into it, it changes the air pressure inside of the drum, which also changes the pitch of the drum.
