Piano Sonata no.1 was composed under my imagery of avant-garde music since 100 years ago; if it is defined that avant-garde music began after world war 1. the four movements were all fixed to 100 bars in four-four time, and all played in 100bpm. Latitudefor four piaonos was composed on the assumption that setting two pianos on the each edge of stage, playing them with the damper pedals on, and setting the other two pianos on the center of stage, playing them with the damper pedals off. this is based on my old idea around 1980. the four pianos are supposed to be softly played with transposing each simple pattern in 60bpm. Arbitrary Projection, Predictive Conversation, Corrupting Correction and Elemental Mapping was composed with some motives and their variations that were made by “copy and paste then edit” technique.
all pieces were composed with pcm piano samples and the sequencer of Apple Logic Pro X. the used piano sample is Bösendorfer for Piano Sonata no.1, Steinway for the other pieces.
