# Lumatone mapping for 53edo

There are many conceivable ways to map 53edo onto the Lumatone keyboard. Only one, however, agrees with the Standard Lumatone mapping for Pythagorean. This is also "Preset 9 — 53-ET Bosanquet" in the official Lumatone manual.

Since 53edo is a schismatic tuning, the best approximation to the 5th harmonic is the diminished 4th. The Kleismic mapping makes playing familiar 5-limit chords easier, but does not quite span the full gamut unless expanded from 4L 3s to 4L 7s, which puts octaves all over the place.

For easy access to single step movements and both the third & seventh harmonics, the buzzard mapping is quite effective.
