Program note

There are two inevitable aspects of consideration when a composer crafts an arpeggio: what it consists of, and its distribution in time. Tradition dictates that more attention is paid to the former while decisions of temporal distribution is left to the performer, denoted at times by squiggly lines. This piece, however, precisely focuses on the diffusion of sounds over a short period of time. Self-developed software is used in order to avoid the feeling of traditional regular pulse-based rhythm and design more organic and complex diffusions of arpeggios. Based on a simple mathematical formula, it simulates the free-fall of several objects of different initial speeds and bounces, and records the timing and the magnitude of impact. In this work, the form, all timings of musical events, and their dynamics strictly reflect the obtained data from the software.
