Prog. notes: A series of pieces entitled various “mirrors” have been composed. As a mirror changes its shape, the image of objects also changes in various ways. In the series, timbre variation by modification of original sound is compared to visual image modification by various types of mirrors. An idea of this piece comes from the visual image given when an object is placed in half-transparent multi-layer mirrors, “Chiekagami” in Japanese. Ray reflection and penetration occur repeatedly, which cause complicated visual scenery. In the piece this visual idea is transformed into that of a hichiriki sound. Hichiriki is a traditional Japanese double reed wood wind instrument. Sound synthesis was done using “Otkinshi” [1], a sound synthesis system which runs on Windows machine. Sound modification functions used mainly here are granular synthesis and sound hybridization. Physical-model-based sound synthesis system, “Sho-So-In” [2] was also used to simulate Sho sound, which is a traditional Japanese mouth organ.
