The voicings
Root, third, fifth and seventh stacked within one octave — the reference voicing (piano; too tight to finger on guitar).
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.
Drop the third-highest voice of the close voicing an octave: a wide, open sound.
Root, seventh and third only. The fifth is dropped — it adds nothing to the chord's identity — leaving a light, clear voicing.
