This is an introductory book for the horn. Includes CD There are some folds on the corners, but the inside is very clean. There are no markings or writings. Finger numbers are written along with the musical score, so if you understand the melody in your head, I think you can play the song smoothly. I think it's important to imagine the sound while playing brass instruments, rather than just using your fingers(´ω`) Several J-pop scores are also included. For those in the brass band club, or those who play the horn as a hobby, how about it?
