This is a textbook for elementary school music education. It has hardly been used. The fourth photo is the table of contents for elementary school music book 1. You can learn about Japanese music culture, instruments, and traditions with these six books. - Set includes: Music Books 1-6 - Language: Japanese - Published: February 10, 2023 I've only glanced through them, but they were stored in a cardboard box, so there is some warping. (See photo 3) Please refrain from purchasing if you are concerned about minor imperfections. Thank you.
