The voicings
Take the close voicing and drop its second-highest voice an octave. The most-used four-note voicing on guitar and in piano left hands. Strings E-A-D-G, frets 3-3-1-4.
Drop the third-highest voice of the close voicing an octave: a wide, open sound. Strings A-G-B-e, frets 6-5-8-7 (position 4).
Root, seventh and third only. The fifth is dropped — it adds nothing to the chord's identity — leaving a light, clear voicing. Strings A-G-B, frets 3-4-4.
Bill Evans-style left-hand voicing: the third on the bottom, the ninth on top, the bass player supplies the root. Strings A-D-G-B, frets 6-5-4-3 (position 2).
The companion rootless voicing with the seventh on the bottom. Alternate A and B so the top voice moves by step through a ii–V–I. Strings E-A-G-B, frets 7-5-8-8 (position 4).
