The patience displayed by a drummer when he/she only gets to play a small percentage of the time in a practice (i.e. fifteen minutes out of four hours) because the melodic instruments can't figure out the chords. This is often confused with 'drummers syndrome', which is when the drummer is blamed for having ADD, but if you read the above discription, ADD is not the case.
Drummers patience is displayed when; the drummer counts off...."1,2,3.." guitarist says, "wait! Is it C to A or.." bassist, "No no, it's C to C sharp..isn't it?" the keyboardist, " NO, it's C for two measures then..." At this point the drummer starts to play on his own, or puts the sticks down and walks away.
