. They are, in the words of the composer, "a newly conceived set of preludes for the modern piano which takes its material from the seven colours of the rainbow, the seven pitches of church modes, and seven metrical units ranging from three to nine beats." Currently ranging from I to IX, these works were written between 1986 and 2001. Each set of Pleiades Dances contains 7 movements, which "are not placed in the order in which they appear in the work for any specific structural or contextual reasons, nor should too much be read into the curious titles [he gave] them." Yoshimatsu, in the preface to these works, encourages free interpretation of these pieces "including tempo, dynamics and frequency of repetition," and suggests that "It may also be enjoyable to play along with the rhythm by a small percussion instrument like the triangle or the tambourine." Each set, however, seems internally dependent, so that within one set of 7, the order can be freely arranged, but the character of each set differs noticeably between each set.

About the Pleiades Dances

Especially prominent in the Pleiades Dances are the composer's use of changing meter

Meter (music)

Meter or metre is a term that music has inherited from the rhythmic element of poetry where it means the number of lines in a verse, the number of syllables in each line and the arrangement of those syllables as long or short, accented or unaccented...

 and unconventional time signatures. Though not always accented in the same way, the meters include 8/8, 6/8, 10/8, 5/8, 7/8, 9/16, 13/8, 1/4, 5/4, 6/4, as well as the more ubiquitous 2/4, 3/4, and 4/4 time signatures. Some compositions written in entirely one meter (such as Arabesque in Twilight, which is in 5/8 ), or consistently alternate between two meters (such as Dance toward West: 8/8 and 6/8; and Dance toward East: 6/8 and 5/8), but the majority change between at least 3 different meters.

Lydian mode

both figure prominently into these works. Slightly Bright Waltz, for example, has a prominently Lydian melodic figure (even though the V7-I relationship of the key of Db is still maintained with a Gb, and Gb is not devoid from the piece). The Mixolydian mode can be seen in many of the Pleiades Dances. Pastoral on Summer relies heavily on the lowered 7th, and the mixolydian cadence of v-I can be found in Memory of Prelude, Scene of Rondo, Pastoral on Summer, Rondo ...Spring Comes Again, Interrupted Faint Prelude, Soft Time Dance, Tender Wind Rondo, Andante on Water, Adagio on Metal, Supple Prelude, Waltz in Obtuse Angle, and others.
The Pleaides Dances are printed by Ongaku No Tomo and grouped into three books: The first book contains Pleiades Dances I, II, and IIa (an arrangement of II for violin/flute and piano), the second contains Pleiades Dances III, IV, and V, and the final book contains Pleiades Dances VI, VII, VIII, and IX. These works have been recorded by, among other pianists, Japanese pianist Kyoko Tabe, who also was the pianist of the premiere recording of Yoshimatsu's Piano Concerto: "Memo Flora".
