Ionian scale essentials
- Interval formula
- 1 · 2 · 3 · 4 · 5 · 6 · 7
- Characteristic tones
- 4 · 7
Practice the A# Ionian sound
- Say and play the scale: Play A# → C → D → D# → F → G → A → A# up and back down, naming the degrees 1 → 2 → 3 → 4 → 5 → 6 → 7 → 1 as you go.
- Hear its defining tones: pause on D# (4), A (7) before landing on A#. Listen for how those characteristic tones color the phrase.
- Connect the positions: Work through all 7 position charts. Start in Position 1 (frets 6–10), 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.
