1. Pick a key and mode. The 7 harmonized chords appear in the grid. Major, Harmonic Minor, and Melodic Minor modes are available. Pro unlocks Harmonic and Melodic Minor.

2. Tap any chord to see its triad on the neck. A variation strip appears -- tap sus2, sus4, or aug to change the voicing. Each variation is saved separately in your progression.

3. Pick your string set. Adjacent uses 3 consecutive strings. Spread (Pro) uses non-adjacent strings for wider voicings. Tap All to see chord tones across all 6 strings.

4. Pick a position to move the voicing up or down the neck.

5. Build a progression by tapping chords in order. Use Prev and Next to step through it. Pro adds Loop, Sound, and Export.

Sound pattern: Each chord plays 4 notes -- lowest string, middle string, highest string, middle string (R, 3, 5, 3 in root position). This pattern stays consistent regardless of what's displayed.

Overlays: Turn on Pentatonic or Scale to see those notes on the neck alongside your chord tones. Teal = chord tones, blue = pentatonic, purple = full scale.

Dot labels:

Notes shows the actual note name on each dot (A, C#, E, etc).

By scale shows each note's position in the mode (1 through 7).

By mode shows R, 3, 5 on chord tones and interval names on the rest.

Below the neck you'll see all available 3-note combinations across the active strings, listed left to right (nut to bridge). Each combination is shown as a role sequence (e.g. 3 R 3) or an inversion name if all 3 chord tones are present (e.g. 2nd inversion). Multiple combinations are separated by and.
