How to Use

Basics

  1. Pick a Mode (Interval or Triad) and a Key.
  2. Set a Start fret (or hit 🎲 Random Start) and choose the Span of frets to view.
  3. Press New Round. The legend highlights the target degree(s).
  4. Click notes on the fretboard that match the prompt. Wrong picks flash red.
  5. Stuck? Hit Reveal to show every in‑scale degree.

Modes

  • Interval: “Select all the 6s” — find every instance of that degree in view.
  • Triad Builder (Ionian): Prompts a diatonic chord (I, ii, iii, IV, V, vi, vii°). Select all its chord tones (e.g., ii → 2,4,6).

Timer

Set Timer (s) and start a round. The big badge in the header counts down. When it hits zero, the board locks.

Practice tips
Use Random Start to avoid memorizing shapes. Try short timers (10–20s) for speed reps. Switch keys frequently.
