Harmony
The chords hiding in any six-note scale, the triad pairs that make one, and a way to put a chord under every note.
G A B D E F♯
Triads 4
Four triads. C, Am and F♯° are gone: each one needed C.
Sixths and sevenths 3
Three four-note chords. Two of them have two correct names: the same notes read from a different root.
Suspended and fourths 9
Nine chords built from 2nds and 4ths instead of 3rds.
What goes under each note
Every chord made only of this scale’s notes that contains the melody note, and the job the note does in it. Tap one to hear it with the melody note on top.

E13
Stacked in thirds from G: 1 3 5 7 9 13. No 11th: that is C, the note this scale leaves out. Every note is still a chord tone of that one chord.
