Since beginning band, I've always been told that you should write on your music to help you with fingerings, dynamics, and musicality, but recently I've been hearing that you shouldn't write on your music unless absolutely necessary like marking repeatedly missed notes or a correction to the piece. I feel that marking down feelings that should be expressed in a passage, writing symbols, and circling emphasised notes helps my playing. Others would argue that the extra writing distracts your eyes from the ACTUAL sheet music where you can already assume which notes should be played out, musicality, etc.

I would like to hear other opinions on this subject and benefits/disadvantages of each.

Is writing excessively on music only common in students, or do artists do this too?
