G Major Pentatonic — Cuban Tres

G Major Pentatonic is 5 notes to the octave (pentatonic family), drawn here across the Cuban Tres's GCE courses with every G marked, so home stays visible from anywhere in the pattern.

Open, sunny, and hard to play wrong — with no half steps there is nothing to clash, so every note sits comfortably over a major chord. Warm, folksy, and singable.

Heard in: Country, bluegrass, folk, gospel, Southern rock, and countless pop hooks — from "Amazing Grace" to "My Girl".

Three courses tuned GCE put a scale in a narrow, honest place: two or three notes to a course, no spare strings to hide on, and the G course sounding above the C beside it — so a run that looks like it descends on paper can rise under the fingers. These maps mark every root so the figure never loses home.

Practise it as a figure, not a ladder: pick four of its notes, loop them as a two-bar phrase against a slow pulse, then slide the same phrase to the next position. That is how this instrument actually uses a scale — as raw material for a repeating line.
