But I always knew when Doug was playing the tympani behind me because it was flawless . I have a memory of Doug playing the rudiments on the snare drum for a music class test . The younger drummers could only wonder at his humble performance as I watched from across the room , mesmerized . At heart , Doug was much more of a set player , a rocker , but his formal technique was amazing .

Question: Why would someone be a good set player ?
Answer: He has to set hair as he plays .A set player can " jam " or improvise with others and not just read a musical score and only go off that .None of the above choices .set means he must sit while playing
