D Chord Form Components & Mods
R = Root, 3 = 3rd, 5 = 5th.
For each of the 5 chords we move [CAGED], we memorize the chord component address within each.
Once we know the components, we use formulas to modify components → build other types.
These are the main mods [modifications] which we can use to create other types of chords using the D Form.
We’ve included the ‘-1 fret’, because once onto the board, and it helps us builds some interesting voicings.
