A Major, Guitar Side

7 notes to the octave, mapped below onto this reader's EADGBE fretboard, with every A called out. Those markers are the useful part mid-bar: a chart moves under you, and the thing you need is where the root went — not where the pattern started.

Bright, resolved, and stable. The foundation of Western tonal music and the most common mode in pop, classical, folk, and jazz.

Heard in: Pop, classical, country, folk, gospel — the default major tonality of Western music.

A chart names the chords and says nothing whatever about the notes between them, so everything a guitarist plays that is not a written chord comes out of a scale that the numbers only imply.

Play it slowly against the audio until the shape stops being a shape, then take it to a chart counted in A and let the numbers pick their own notes out of it.
