Prog. notes: The word Masokagami represents a limpid mirror used in religious services in ancient Japan. It also contains the words for `shine' and `image's. In music or acoustic signal, it is very important to repeat or overlap the same information over and over again. In the counterpoint, which is one of the fundamental composition techniques, musical order is produced by using the repetition of theme's variation, such as inversion, retrograde etc. In the meantime, the acoustic signal gives us different impressions in relation to the delay time, such as timbre variation, reverberation, and echo.
The concept of “repeating the same information” is important not only in music, but also in visual art and even in daily life. Various mirrors are tools to reflect or repeat rays. By choosing a mirror as the theme of a piece, the composer tries to evoke a double effect, conveying the impression of the mirror and musical unification. Lyric texts are referred to “Man'yoshu”, which is an eighth century style of poetry, consisting mainly off tanka poems, the Japanese ode of 31 (5+7+5+7+7) syllables. Three tankas are selected because of their relevance to a mirror,
