This is a fun textbook from Saber Company for learning three types of notes and rhythms. It was used when I first started piano, and has some page-turning creases and a teacher's "Excellent!" mark. However, the notes haven't been colored in, so I couldn't bear to throw it away. I think it's still a usable textbook. "Yoku Wakaru Youji no Onpu to Rizumu: Ookina Kabu no Maki" (Understanding Rhythms and Notes for Young Children: The Turnip) has been colored in by a child, as shown in photo 6. This is a USED item, so please understand before purchasing. Individual sales are also accepted.
