【Item】 DVD-BOX of Music Theory for Wind Band - Useful for Instruction and Performance For Promotion Wind Band Instruction Material Masamichi Amano Seiji Sagawa Eiji Suzuki Details unknown as it was given to me by a family member. Please check the images. This DVD-BOX is designed for wind band instructors and performers, and explains music theory and musical rules in an easy-to-understand manner. Everything in the images is included. A promotional label is affixed to the box. The case has some damage, but the disc surfaces are quite clean. It seems like it hasn't been used much. "Condition of item" refers to the disc surface condition. I have checked the playback of only the first part. I have not checked the operation of the rest. Since it is used, please refrain from transactions from the beginning if you are sensitive. It will be simply packaged with bubble wrap and placed in an envelope, and shipped via Yu-Packet Post.
