Hello, I am a percussion major out here in colorful Colorado. I was curious
if any of you have put the Mayuzumi Concertino (For Piano and Xylophone, NOT
Orchestra and Xylophone) in Finale or if anyone has seen it in anything other
than manuscript form. It is very difficult to read and it is hard finding an
accompaniast that will put up with the messy score. If anyone could help, I
would greatly appreciate it. Thanks much!

Have you really had a problem finding a player? I would suggest going through the music school and have them get a student acc. major or someone who is on staff.
I wouldn't try to put it in Finale or Sibelius becasue that option will just waste your time.

Good luck
