i just recently lost an opportunity for a recording gig because i did not know the Nashville number system. so of course i google this to look into it so i can add it to my arsenal. ive searched every combo of the words i can think of and have no idea how it pertains to the drums. if any one can explain or send me somewhere that explains that would be rad. i understand how it works for keys and octaves and whatnot now but i dont know how it would transfer to the drums.
