《Notebook of Sounds》 is a five-movement piano duet suite. It was composed in 1985 at the commission of Toshiba EMI for their educational record series. It embodies the joy of piano duets that Miyoshi experienced in his childhood through the works of Mozart and Schubert. He described this as the wonder and emotion of a single piano beginning to breathe sound as a living entity, through the hands of oneself and others.

Prelude (approx. 2 min)

A somewhat nostalgic theme, played by the Primo's right hand, develops supported by the other three hands. It is in ternary form.

Passepied (approx. 1.5 min)

Within a light 2/4 meter, a lively "Staccato Accentuare" theme is repeated. The contrast with the legato section in the middle is striking.

Romance (approx. 2.5 min)

A beautiful theme is sung with sustained breadth, carried by the swaying rhythm of 6/8 meter. It is in ternary form, with a dreamlike middle section.

Courante (approx. 1 min)

The piece unfolds with a somewhat humorous character within the flow of 12/8 meter. It is in ternary form with a coda.

Finale (approx. 2 min)

Beginning with the Primo's rapid triplets and the Secondo's sharp chromatic scales, it is in ternary form. The breathtaking interplay between the two performers conveys the true essence of piano duets.
