XronoMorph – Explore Rhythms in New Ways

Check out this awesome free application from Dynamic Tonality. It offers a new way of approaching rhythm composition.

XronoMorph utilized mathematical approach that uses two main methods: perfect balance and well-formedness.

Check out the video demo on the bottom.

A few words from the developer.


Perfectly Balanced and Well-Formed Rhythms

The mathematical principles utilized by XronoMorph are perfect balance and well-formedness (MOS).

Perfect balance is a generalization of the polyrhythms found in many African and jazz musical traditions. A rhythm is perfectly balanced when the mean position (centre of gravity) of all its rhythmic events, when arranged on a circle, is the centre of that circle.

Well-formedness is a generalization of the additive rhythms found in aksak (Balkan), sub-Saharan African, and progressive rock musical traditions. Well-formed rhythms contain no more than two interonset intervals, arranged as evenly as possible. WF rhythm are typically nested by faster WF rhythms, which in combination form complex interlocking rhythmic hierarchies.

More detailed explanations of the two principles are provided in the videos on the XronoMorph YouTube channel and in the following papers:
