Altered scale essentials

- Characteristic tones

Practice the F# Altered sound
- Say and play the scale: Play F# → G → A → A# → C → D → E → F# up and back down, naming the degrees 1 → b2 → #2 → 3 → b5 → #5 → b7 → 1 as you go.
- Hear its defining tones: pause on G (b2), A (#2), C (b5), D (#5) before landing on F#. Listen for how those characteristic tones color the phrase.
- Connect the positions: Work through all 7 position charts. Start in Position 1 (frets 2–6), then repeat a short phrase from the root in each shape. Use the full fretboard chart to find the next F# as you move between positions.
