CD set of classical masterpieces, all 6 discs. - CD Title: Zen-On Piano Pieces: Piano Masterpieces 1-6 - Publisher: Columbia Nippon Columbia Co., Ltd. Made in Japan - Supervision: Koichi Nomura - Piano Performance & Instruction: Atsuko Kanzai - Song Commentary: Koichi Nomura I bought these CDs intending to listen to them carefully when I had time, but I haven't had the chance and they've been in storage for a long time, so I'm putting them up for sale. The paper materials and cases show signs of yellowing, stains, and scratches, but the CD bodies are very clean. All have been tested and are working. They are all famous songs, or songs you've heard somewhere before. I hope you can use them for piano lessons or during tea time. Thank you for looking.
