Every chord type on C (tap a major key on the circle to change it; in print, any red root uses these colours and a blue root swaps them). Numerals are relative to the root. Dots = string colour of each chord tone, root first; split = notes on the root's row + notes on the other row.

An inversion never changes the colours: every note stays on its row; only its hand and octave move.
Tonnetz: C major and its P, L, R neighbours
- Rows: fifths. Down-right: major thirds, each one string row (red or blue stripe). Down-left: minor thirds.
- ▽ major, △ minor. Every triad is 2 notes on one stripe + 1 on the next.
- R C → Am: G → A, whole step, same row.
- P C → Cm: E → E♭, half step, changes row.
- L C → Em: C → B, half step, changes row.
