HarmoGnome is a metronome for harmonic rhythm.  Its one-hot approach to tonality brings an intuitive and radically efficient tool to musical practice.

You should use this application:

1) if you play scalesbecause your ears are faster than your fingers

2) if you want to improvise over harmoniesbecause  you can play over chords by feel, without a lot of theorizing.

Here are a couple of movies to get you started: 1) intro; 2) tour; 3)MIDI out example; 4) blues over the network



We’ll soon be adding some flexibility and expansions, but first we’ll get the thing out there…


1 ) Drag and Drop sequence creation -> sequences can be created, saved, and shared in a twitter-sized format

2) MIDI in – Analysis -> the algorithm has the capacity to analyze and extrapolate from live audio.  Uses should include analysis of repertoire, dynamic/reactive music, and tagging of audio for live computer-based improvisation.

3) HarmoGnome requires three capacities a) an ability to play sine waves; b) an ability to calculate in binary; c) an ability to dynamically draw dot buttons.  It should run on anything – weather, time, and funding permitting.  Android and Raspberry Pi versions can be reasonably imagined.

4) Support for alternate tunings. This may be a rabbit hole. But at least the A can move around to 442 or something.


A last note about harmony: It’s not just that it can be in binary. It’s that it should be in binary. Because harmony itself can be employed as a special kind of neural network, a programmable and dynamic way of identifying possibility rather than fact.
