Augmented Triad Scale — All 12 Keys

Augmented Triad in all 12 keys for guitar, bass, ukulele, and piano — notes, scale degrees, and free printable charts. Root, major 3rd, and raised 5th — a symmetrical, unsettled sound favored in jazz and impressionist classical music.

How the augmented triad is built

The augmented triad has 3 notes, with the scale degrees R · 3 · #5. Those degrees stay the same in every key — only the note names change — which is why the same shape moves up and down the neck.
