C Major Pentatonic on Vihuela

C Major Pentatonic runs 5 notes to the octave. Below it is mapped onto this instrument's A–D–G–B–E fretboard with every C marked, because what a player needs mid-number is not the pattern but where the root is when the harmony moves under it.

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".

The armonía is not a soloing section, so a scale here is diagnostic rather than melodic: it is how a player finds which tones a grip is actually putting in the air on a neck whose octaves do not run in order.

Take it slowly against the playback until the geometry stops being geometry, then put it under a number in C and let the written line pick its own notes out of it.
