A harmonic lattice diagram (lattice) is an instrument to visualize relations of tones. It's a projection of a multi-dimensional structure onto a 2D screen.
The Tonnetz is the lattice that represents 12edo's mapping of 5-limit intervals. Vogel's Tonnetz is a 7-limit version of Euler's 5-limit Tonnetz.
Examples
-
A square lattice representing marvel temperament. -
A hexagonal lattice representing 41edo's mapping of 5-limit intervals, using ups and downs notation. -
A hexagonal lattice representing a subset of 7-limit intervals, using color notation. -
A torus of notes in 15edo, notated by porcupine notation with LH-NiceIonian as the base scale.
