Fig. 11 employs the 7sus4 voicing in a jazzy R&B-style riff. We use a similar feel in Fig. 12, but use the stacked-fourth voicing concept. We combine both open-style voicings in Fig. 13.
We can also make our voicings denser by having the lower two notes be only a minor second or major second apart. Fig. 14 runs the chord scale up with this tight voicing. You can think of the voicing as a rootless 9 chord with the 9th degree of the scale (or 2nd degree, if you like) on the bottom. Or you could think of it as a 7th chord with the 7 on the bottom—or a mixture of both. So the chord-scale could become Em9–A7–Bm7–A9–Dmaj7–Em7–F#m7–Em9. Because there are only three notes in the voicing, it’s certainly open to interpretation—and wide open for music making. Fig. 15 uses three-note voicings in a riff that starts off with a typical Em7 barre chord voicing, so we get a nice mix of a stock funk chord with chimey cluster chords.
