Understand the sound
A♭7: from a pattern to a musical choice
What gives A♭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 C, and degree ♭7 is G♭. Play A♭ 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 A♭ on string 6, fret 4. The next note C is on string 6, fret 8. 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: A♭ · C · E♭ · G♭. Then play a two-bar phrase from memory and leave two bars of silence.
