Query: The Ongaku Masters

I purchased this anthology based on a piece played on NPR Radio. It was hypnotic. This set is a musical journey spanning several thousand years to present and played on original instruments of the time. As a novice to Japanese music, the accompanying booklet was invaluable in that it taught me how to listen and appreciate totalling different sounds. While Western music concentrates on melody and harmony, Eastern music views tone as paramount. The tones expressed are quite complicated and intricate and, in some cases, cover the lifespan of a note, including its silence. I highly recommend this set for it's enlightenment, excellent production/explanation and beauty. It is a work of art.
