“Michelangelo’s Pup” was composed in 1993. ‘Michelangelo’ is the name of a computer virus that was prevalent at the time. The song begins with the melody of “Waltz in d flat, Op.64, No.1 (‘Minute’)” by Chopin. However, the elegant melody is quickly deformed and diffuses violently. In the confusion, Chopin’s beautiful melody appears sometimes suddenly. While fragmented “Waltz in d flat, Op.64, No.1 (‘Minute’)” is incorporated everywhere and the song develops insanely.

In the music, notes are very colorful. The original melodies of “Waltz in d flat, Op.64, No.1 (‘Minute’)” are yellow, the chromatic melodies are pink, the loud chords are green, the quiet chords are blue, and the leaping phrases are orange. The colored pencils used for the notes were attached to the painting, ‘Michelangelo’s Name’, which was an European souvenir from pianist Hatsue Nakamura who premiered this song.

Matsudaira has pioneered his own composition technique while absorbing avant-garde music such as Total Serialism and Music of Indeterminacy. In this work, using the technique of Musical Quotation, he expresses a scene where various events occur completely irrelevantly.
