This is a trombone instruction book, Volume 1 of Kopprasch's "60 Selected Studies for Trombone." - Title: SIXTY SELECTED STUDIES FOR TROMBONE - Author: KOPPRASCH - Publisher: CARL FISCHER I purchased this about 15 years ago. I used it frequently, so the cover has some dirt and scratches. The binding had come loose due to deterioration, so I removed the staples and left it unbound. The music inside is clean with no markings, so I hope you can find value in it as a copy source or for scanning. Please understand that this is a used item and consider this before purchasing.
