Fully dim 7 Chords on 4321 Strings
Let’s explore the fingerings on the 4-3-2-1 strings. First, the voicings, then we’ll make modifications in the next session.
These have an interesting sound, plus the ability to blur tonality. You can finger the chord at the nut, or just start at the 3 fret. Play it at 3, then at 6, 9, 12, 9, 6, and 3 (should sound familiar). Strum or fingerpick.
The tone names are different for different keys, but you can think about the tone names in any preferred way.
Each of these 4 tones is a leading tone (half step down from key root) in one of the Harmonic minor keys. We saw that G# is leading tone in Am.
- F in F#m (called E#) – chord is spelled E#-G#-B-D
- B in Cm – chord is spelled B-D-F-Ab
- D in Ebm – chord is spelled D F Ab Cb – (in D#m, it is called Cx – C double sharp)
Next, we’ll create 4 Dominant 7 chords by modifying each tone, in the same way.
