“Kurai Umi” (Dark Waters) is track number 20 of the “Moods and modes” project.
The piece is a trip to a “Japan of the mind” (since sadly I’ve never been there), suggested by a Shakuhachi flute, a Koto and a Taiko drum.
The melody is in the Insen pentatonic scale, somewhat similar to the E Phrygian mode.
