I felt the staircase of colors created by rainbows, and created the palette of sounds with a sense of colorful fantasy. I wish to create the refreshing feeling when encountering a rainbow, the cheerful sensation when the rain clouds clear and transform into a brighter moment. I want to express that pleasant moment.The prism's staircase is painted with seven colors, each color creates seven unique fantasies, without blending. Percussion can produce infinitely varied tones to enable a rainbow fantasy. With the combination of instruments, the tempo, dynamics, and phrasing - I am conscious of color throughout. Each instrument perfectly displays its own color. From the rainbow bridge, a space of colors expands, lively nature is born. I created a stage for the drama and depth of colors orchestrated by sound. Rainbow colors entail red, orange, yellow, green, blue, violet and indigo. Please imagine which instrument represents which color.
