Tetsuya Kumakawa Selection: Music for Ballet Class - Reverence (CD) The first ballet lesson CD supervised by Tetsuya Kumakawa, Artistic Director of K-Ballet Company! He selected the most suitable music for lessons from a wide range of musical genres. You can naturally develop a sense of rhythm and musicality during your daily lessons, and it's also perfect as background music to wake up to in the morning. It's practically new, having only been ripped to a computer once.
