	Voices Phantasma - Flame	Кото : Yoshimura Nanae
This work was composed for "Nanae Yoshimura Koto Recital" (Oct. 5, in TOKYO FM Hall) in autumn, 1992 and first performed. It is a variation with seven sections. The theme is a lullaby of Iwate Prefecture, which is played or sung at the same time (ad libitum), in the last part. The 1st section gradually starts with the musical idea, such as the origin of music, but it is pulled back to the situation before the origin again. In the 2nd, there is the melodious occurrence, though, it cannot leap as it is bound by the primitive power of a low tone. In the opening of the 3rd, we can hear the free sound movement, but this time, the unrealistic sound of the treble interrupts it very often and constantly. We can hear the natural and light tune at last in the 4th, the rhythmical step in the 5th, the firmer motion in the 6th. And in the 8th, it shows the world of a folk music, then, a maze of the various tune and sound is closed Additionally, from the 3rd to the 6th, a finger movement on the strings is repeated in the same forms and the opening string (that is a register) the only difference. However the melody is not similar figures because of the special tuning. The tuning consists of sounds; C, F, A-flat, B-flat, C, B-flat, F, G, A-flat, B-flat, B, C, C-sharp, D, B-flat, B, F, F-sharp, G, G-sharp, A. In the bass register an interval is wide, and in the treble it is narrow. - Minao Shibata
