Stellar Resonance for Cello and Piano 5 graphical scores by the Mandelbrot’s mapping

This music is composed for cello and piano based on a beautiful mathematical function Mandelbrot’s mapping. I developed the original computer program to calculate the nonlinear mapping of the Mandelbrot set to determine the timing, pitch, and duration of the notes. The variation of score depends on the initial value of calculation. As shown by the colored (e.g., red and yellow) lines in the following figure, the output values are calculated recursively and depend on the initial parameters. I mapped these successive values on the score as a graphic score. However, I did not simply put the calculated notes on the score directly. I ran the program many times while changing the parameters of the Mandelbrot set to calculate lots of sets of notes, and selected only agreeable and beautiful notes to this piece carefully. The titles of each movements mean the initial values of Mandelbrot’s mapping used to calculation the consecutive notes.

Score https://www.cello-maker.com/research/music/japanesemusic-score.html#3 I asked my daughter to draw pictures around the sheet music, letting her imagination run free with images of cicadas and the countryside. It's an intro plus six bagatelles (like a collection of little pieces, meaning trifles). The order is chosen at the performer's whim.

Masao Yokoyama: Nocturne Concertante for Solo Cello and String Orchestra

Cello concert based on Japanese traditional music.

This music was composed for solo cello and string orchestra in 2021. The normal image of “nocturne” in classical music may be noble and elegant, but the image in this music is a little different. I composed the music based on the inspiration of a creepy and holy place such as a temple in a dark forest where ogres and demons exist. I hope the audience may feel something holy inspirational and ironic in this music. This piece was nominated for the final pieces at the Alfred Schnittke Competition Composers 2021.
