C Major Pentatonic, Guitar Side

5 notes to the octave, mapped below onto this reader's EADGBE fretboard, with every C 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.

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".

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 C and let the numbers pick their own notes out of it.
