Japanese musical scales

A variety of musical scales are used in traditional Japanese music. While the Chinese Shí-èr-lǜ has influenced Japanese music since the Heian period, in practice Japanese traditional music is often based on pentatonic (five tone) or heptatonic (seven tone) scales. In some instances, harmonic minor is used, while the melodic minor is virtually unused.
