“In” signifies the origin of the whole phenomenal spaces which exist in the universe. Music is “the arts of time”, which embodies the essence of “In”. This music expresses this concept through the use of the instrument made of Sanukit stone. Sanukit stone is the symbol of the original material created at the moment of cosmo-genesis, and the instrument looks like a beautiful sculpture. The sound created by the stone is truly beautiful, gentle, and romantic sacred sound. This work is an album of sacred sound created by the stone with the theme “Creation, Gratitude, Mercy, Beloved” This sacred sound created by the stone is also used for the psychotherapy in many medical institutions. Sanukit stone generates a frequency of over-8000Htz, and it is reported that this supersonic wave and wavelength improves the mental balance, and brings the significant effect on the activation of brain and human cells, and works to refresh minds and body with beauty effects. Moreover, in the history of the arts of music, the sound breaks the conventional concept (the range composed of 88 tunes in the temperament), and predicts the creation of new “sound” in the 21st century. We are convinced that this work and the following series of works will play the important roles for presenting the value judgments and the direction for the new arts.
