CAGED Map is evolving: positions and fingerings are reviewed and corrected progressively.
Start with a few notes and a short phrase. In the demo, choose C, find C, E and G, then locate them in the arpeggio and the C major scale. Play slowly, vary the rhythm and leave space. Aim for a phrase you like hearing rather than covering every fret.
Chord tones give you useful targets. Over C major, they are C, E and G. Use them to begin or end a phrase, then explore the other notes in a scale that suits the song. Rhythm, note length and accompaniment also affect what you hear.
A chord combines notes played together. An arpeggio plays chord tones one by one. A scale organises notes that can form melodies and chords. In the C major demo, the C chord and its arpeggio share C, E and G; the scale also contains D, F, A and B.
In a C major progression, the C major scale contains the notes of all three chords: C = C, E, G; F = F, A, C; G = G, B, D. CAGED Map Lite lets you compare them in one fretboard area. Targeting the active chord tones helps you hear the changes.
No. Fingerings show where to place your fingers; the Notes and Intervals views help you name and understand what you play. Knowing a few guitar chords makes it easier to begin.
The CAGED system uses five chord shapes: C, A, G, E and D. They connect chord, arpeggio and scale positions on the fretboard. In CAGED Map, you explore those relationships one area at a time.
It is a visual and audio tool for finding your bearings, not a complete course. Rhythm, phrasing, listening and playing songs remain essential.
