This piece consists of a theme and eight variations (the final variation also serving as a coda).

Theme

The theme is based on the folk song "Kagome Kagome" and employs a simple texture with a bass line. Occasionally, imitation-like responses are heard, but these are not elaborate enough to be called true imitations; rather, they serve as interjections.

Variation 1

This is a prelude-like ascending arpeggio, but instead of directional harmony, it possesses the character of an echoing call, using only the four notes a-d-e-g. The reverberation is beautiful.

Variation 2

This variation is composed in a style that clearly imitates the koto music idiom, possessing an "homely" atmosphere of old Japan.

Variation 3

In stark contrast, this is a modern style with a dance-like, repetitive accompaniment. Midway, the original form of the theme disappears due to chromatic runs, but it returns in the final four measures.

Variation 4

Double stops in fourths (in the bass) and adjacent three-note clusters alternate rhythmically. The theme is placed in the bass.

Variation 5

Based on melody and harmony composed of the five notes a-B-d-e-g, and by interweaving chromatic notes, a unique, undulating sound is created. The trace of the theme is no longer discernible.

Variation 6

Conversely, this is a variation featuring arpeggios that clearly articulate the theme. It again evokes the koto, but only high registers are used, and chromatic movements are also heard.

Variation 7

This variation is in the modern, dance-like style of Variation 3. It involves hand crossing and has a strong aspect of technical exercise. Midway, koto-like arpeggios are interspersed, creating a stylistic contrast.

Variation 8 (Coda)

Its character continues from Variation 7, but an even more modern sound is pursued, with features such as seventh-interval leaps. The combination of melody and tremolo in the latter half is reminiscent of Debussy's piano writing. The theme is almost entirely deconstructed.
