Yamaha original music notebook (2-staff), horizontal type. The inside pages have two staves, and there's a mini music theory section on the inside cover. The regular price is 880 yen for a set of 5, but since one notebook has been used, I'm selling a set of 4. I took them out of the bag for the photos, but they've been stored in the bag since I bought them, so they're in very good condition. [A Word from Dad] My child also started practicing writing notes with this notebook. The staff lines are wide, which is perfect for tracing notes or sticking stickers. Looking back at the first notes and practice records that children write is truly a treasure. In that sense, I felt it's good to have a few notebooks on hand. Since it's not a notebook you'll use up quickly, "Having a few on hand for peace of mind" is enough. Your child will grow quickly and need the next step. Thank you for looking.
