i think you should learn the accordian...it's done wonders for weird al!
Guitars are for getting chicks. Drummers get sloppy seconds. Bass players get.. Oh, no. Never mind.
thing is, you can practice drums without a drum set. you can practice in your head even.
Not sure if I agree with this statement....
Maby you can explain it?
drumming is about timing, about hand eye coordination, and about technique more so than about musical "talent", or "scales", etc.
with a guitar, it's more about scales, chords, memorization certain finger placements, strumming patterns, etc.
if you want to practice a mixolydian scale, you kind of need a guitar in hand to practice it and fully reap the benifits of the practice.
if you want to practice a paradiddle, you can do that with your hands on your knees, or your teeth inside your mouth, or by simply repeating "right left right right, left right left left" over and over in your head. if you want to practice your hand/foot independence, you can sit in your chair at work and bounce your high hat foot in time with the 1, 2, 3, 4, while bouncing your bass drum foot with the 1, 3, 1, 3, and then throw in your snare hand on the 2, 4, 2, 4, and then for fun take your other hand, and play a 1,2,3, 1,2,3, in a 3/4 pattern to try to mess yourself up.
just being a long time musician, and player of both insturments, it's my opinion that because of these reasons, it's MUCH easier to "practice" drums, or learn drums, and get much better on drums, without ever having to touch a single drum.
