This is a set of practice sheet music used in high school club activities. SUPER SOUND TRAINING → No noticeable markings. 3D Band Book → Some pages have markings, as shown in photos 4 and 5. Tipps → In poor condition, as shown in photos 7, 8, and 9. There are scribbles and rust stains. Trombone Textbook Method → There are markings on several pages, as shown in photo 10. I think it's within the range of the equipment. Sheet music holder → It has been reinforced in some places, and there are white scratches, but I think it can still be used. I joined the brass band club as a beginner in high school and practiced using these materials. Everything in the first photo is included. Thank you for looking.
