Bayes GmbH
Bayes builds PitchGrid.
Bayes GmbH is the company behind PitchGrid, a software and research effort focused on making non-traditional scales, tonal systems, and intonations musically usable.
Our work centers on tools, interfaces, theory, and teaching that help musicians explore new tonal worlds without getting lost.

What we focus on
Musical software
Plugins, tools, and workflows for navigating alternative tonal systems in a practical way.
Interfaces and instruments
Mappings, layouts, and interaction concepts that make unfamiliar harmonic spaces playable.
Research and teaching
Theory, explanation, and educational material that help new tonal cultures become legible.

PitchGrid is Bayes’ main product and long-term mission. It starts from Western tonal legacy, but opens a path into structured alternatives: new scales, new instrument layouts, new compositional workflows, and eventually new musical cultures.
