Although this music requires high technique to perform, Hiro enjoyed thinking of each faces of members who could easily play any sounds he wrote.It was commissioned and first performed on 4th December, 1999.This music is inspired by various kinds of sounds from water stream, such as spring water, a mountain stream, murmuring, waterfall, river, and so on. These sounds always create different rhythms that amuse people. There are many expressions on water in Japan ,and Hiro likes a phrase that "The flowing river never stops and yet the water never stays the same".

Hiro hopes this music will be loved by many people and played all over the world with wishing blessings of water will sustain forever.
