A set of Glass Harp which has pressure sensors installed under 21 wine glasses is illuminated by LED lights when the performer touches the each glass. Illuminated glasses and water merged into each other, and this visual effect and the sound represent the concept of between water and ray.
21 notes were chosen from the sound spectrums exhibited by FFT analysis, based on E♭as a base tone and B♭as a sub base tone. Those 21 notes are performed effectively by various glass harp techniques.
