This program uses spirals to generate microtonal musical tunings/scales. The spider web harp let's you play to test scales and find chords and progressions, often appearing geometrically. The scales are very harmonic and musically useful. Equal temperaments also appear (not in very efficient spiderwebs). it's a web app and should run in any modern Browser. download link in next video https://www.youtube.com/watch?v=GxmSsSl0rG4
