C Guitar Scale
Learn how to play the C scale across the guitar fretboard using the CAGED and Pentatonic systems.
CAGED System
The CAGED system is a method for visualizing and navigating the guitar fretboard. It is based on five open chord shapes—C, A, G, E, and D—that repeat across the neck. Connecting these shapes helps you play scales, chords, and arpeggios in any key and position.
Each shape can be linked together to cover the entire fretboard, giving you freedom to shift between chords, scales, and improvisation across the neck.
Modes in the CAGED System
- Ionian (Major) – Bright, happy sound.
- Dorian – Minor scale with a jazzy/bluesy flavor.
- Phrygian – Dark, exotic, Spanish-like sound.
- Lydian – Dreamy, floating quality.
- Mixolydian – Major with a blues/rock edge.
- Aeolian (Natural Minor) – Sad, emotional tone.
- Locrian – Dark and unstable, used for tension.
Scale Boxes
Scale boxes are patterns on the fretboard that help you play scales in small, manageable areas. Each box corresponds to one of the CAGED shapes. Learning all five boxes gives you a complete map of the scale across the guitar neck.
Pentatonic System
The Pentatonic scale is a five-note scale that works in almost any musical context. It removes two notes from the full major or minor scale, making it simple, powerful, and easy to use. This scale is the backbone of rock, blues, pop, and many traditional styles worldwide.
Pentatonic Boxes
Just like the CAGED system, the pentatonic scale can be played using five connected box patterns across the neck. Each box contains the same five notes, but in different positions. Learning all five positions gives you freedom to solo and improvise anywhere on the guitar.
