Drop 2
F · B♭ · D · A♭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 D-G-B-e, frets 3-3-3-4.
Drop 3
D · B♭ · F · A♭Drop the third-highest voice of the close voicing an octave: a wide, open sound. Strings A-G-B-e, frets 5-3-6-4 (position 2).
Shell (1–7–3)
B♭ · A♭ · DRoot, 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 1-1-3.
Rootless A (3–5–7–9)
D · F · A♭ · CBill 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 5-3-1-1 (position 1).
Rootless B (7–9–3–5)
A♭ · C · D · FThe 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-B-e, frets 4-3-3-1.

Understand the sound
B♭7: from a pattern to a musical choice
What gives B♭7 its identity?
The third and flat seventh form a tritone. Hear those two notes first, then hear how they move when the dominant resolves.
Here the third is D, and degree ♭7 is A♭. Play B♭ in the bass and compare these voices individually before combining them.
Choose a useful voicing
Start with the smallest displayed shape you can play cleanly. Move its highest note into a comfortable register and listen for a clear melody above the chord.
Sound the strings separately before playing them together. If a note is muted, adjust the finger angle instead of squeezing harder.
Your guitar checkpoint
Start with B♭ on string 6, fret 6. The next note D is on string 6, fret 10. Name both notes aloud before playing, then find the same two pitches in another octave.
Before moving on, close the diagram and name the notes: B♭ · D · F · A♭. Then play a two-bar phrase from memory and leave two bars of silence.
