Every chord here is computed from the notes your fingers actually press — then named, spelled, and explained. Move any shape up the neck and watch the same intervals make a new chord.

Notes on the neck
Every note on the whole fingerboard at once. Pick a root to colour each position by its interval, or choose a scale to light up just its notes — with the chord skeleton (1·3·5·7) coloured inside it and the key's diatonic chords listed below. The same note keeps reappearing in a pattern as you travel up a string or across to the next one.
