Thank you for viewing. Rhythmic Bayer, Volume 1 & 2, 2-book set 2 books for 2400 yen + tax (at the time of purchase), published by the Rhythmic Research Center A keyboard introduction textbook applying the principles of rhythmics. Used only once during a training course at the Rhythmic Research Center 7-8 years ago, and then stored at home. There are about 10 instances of pencil markings (see images 2 and 3) in Volume 1, and a few in Volume 2, which I will erase before listing. The spine of Volume 2 is sun-faded (see image 4), so please refrain from purchasing if you are concerned about this. Please consider purchasing the set. ☆Combined Purchase Discount☆ 200 yen off for 2 items, 300 yen off for 3 items from sheet music, magazines, and CDs. I will respond in order of comments, but please understand if someone purchases before I can respond. #Rhythmics #RhythmicResearchCenter #SheetMusic #EducationalMaterials #Bayer Type...Musical Instruments/Music
