hey dudes. i was having an argument with a friend the other day about whether its more professional to be more adept at playing by sheetmusic or by ear. i can hear both sides, because when you have sheetmusic, you can play anything! you arent limited to what you know. on the other hand, if you know a song, but you dont have the sheetmusic, then your messed over. so i just wanted to hear your opinions on this. thanks so much.
