Once you know the basic system of movable major chord shapes (the C, A, G, E and D forms) it is possible to alter some of the notes to create other chord types, e.g., minor chords. The positions of the root notes remain the same regardless of the chord type. Shown in the following diagram are the five basic forms as open position minor chords.
Like major chords, these minor forms can be joined end to end in the same order (CAGED) to cover the whole fretboard. The following diagram shows the five basic forms of movable minor chords.
The following example demonstrates all five forms played as C minor chords. Practice them slowly and memorize the shapes and positions of the root notes. When you can do this easily, transpose them to other keys.
