1. Pick a root note and mode. The 7 harmonized chords for that key appear in the grid below.

2. Tap any chord to see it on the neck. A variation strip appears below the grid -- tap sus2, sus4, or aug to swap the voicing. Each variation you pick is added to your progression as its own chord.

3. Pick your string set. Adjacent uses 3 consecutive strings. Split (Pro) uses non-adjacent strings for wider voicings.

4. Pick a position window to move the chord 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.

Dot labels explained:

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

By scale -- shows each note's position in the mode scale as a number (1 through 7). Helps you see how the chord sits inside the scale.

By mode -- shows R, 3, 5 on the chord tones and interval names (b3, b7 etc) on the other notes. Helps you understand each note's relationship to the chord root.
