Make a short phrase
Play A♭ – C – E♭ – G♭ in quarter notes at 60 bpm. Repeat starting from C, wrapping back to A♭. Do not speed up until every attack is even.
Hear it in context
Alternate C and G♭ above a sustained A♭. These are degree 3 and ♭7. End a four-bar phrase on either one instead of always returning to the root.
Listen for this: A♭7 has the colour “tense, pulling toward its resolution”. Name the degrees as you play, so you can recognize the sound in another key rather than remembering only a shape.
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.
Turn the arpeggio into a melody
Try C – E♭ – G♭ – A♭ as quarter notes, then repeat the first note and omit the last. The second phrase uses the same harmony with a different shape.
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.
