Practice the A Diminished Half-Whole sound
- Say and play the scale: Play A → A# → C → C# → D# → E → F# → G → A up and back down, naming the degrees 1 → b2 → #2 → 3 → #4 → 5 → 6 → b7 → 1 as you go.
- Hear its defining tones: pause on A# (b2), C (#2), D# (#4), F# (6) before landing on A. Listen for how those characteristic tones color the phrase.
- Connect the positions: Work through all 5 position charts. Start in Position 1 (frets 5–9), then repeat a short phrase from the root in each shape. Use the full fretboard chart to find the next A as you move between positions.
