To perform on any device with a web browser, ideally on a smartphone. Variable duration. Uses HTML5 Web Audio API. It is currently compatible with most modern desktop browsers, Chrome on Android phones and Chrome or Safari on iPhones.
Develop the performance by subsequently adding individual notes to the repeating sound mix. Specify the individual note to be added by setting its relation to the given ground frequency. This you do by changing the multiplier and divisor. The new note will be M/D*F, where M is the multiplier, D the divisor, and F the main frequency. Generally you should increase or decrease either multiplier or divisor in turn, always in a different order. For example: 1/1, 2/1, 3/1, 3/2, 4/2, 4/3, 5/3, 5/2, etc. Thus the growing sound mass should increase according to some variation on the harmonic series of the ground frequency. Each new note is added to the tone mix at a randomly selected place inside the repeating time cell. Each change is introduced to the sound mix by pressing the Submit button or swiping right on the Swipe panel. Occasionally, do one of the following changes:
Duration is free, but usually around 20 minutes.
