Fantasy Prelude Miscibly Interfused is a piece for solo piano of 2020 derived entirely from the first movement of Ludwig van Beethoven’s Sonata No.14 Op.27 No.2 in C-sharp minor (Sonata quasi una Fantasia), popularly known as the “Moonlight Sonata”, and Johann Sebastian Bach’s Prelude No.1 in C Major from Book 1 of the Well-Tempered Clavier, BWV 846.

The piece faithfully interfuses the above-named music, whereby Bach’s rhythms invariably carry Beethoven’s pitches and vice versa. According to the principle pitch→rhythm (pitch carried by rhythm), these two interfusing processes are here labeled “Beethoven→Bach” (which launches the piece) and “Bach→Beethoven” (which starts in the eighth bar). Varied is only the extent to which the interfused notes are muted or presented. For instance, though “Bach→Beethoven” starts in bar 8, it is audibly evident only from bar 9.
