I use this 0.9 mechanical pencil for notations on my sheet music instead of a 2 pencil... It works great. Notations using a mechanical pencil with smaller diameter leads just don't show up well on stage.. . I keep this mechanical pencil in my pocket, while a 2 pencil has to travel in my gig bag, where the tip can be broken. So whenever the conductor makes a change, like make that mezzo piano at measure 40, the change is made, and it will be played exactly as requested next time.
