Three Focused Training Modes
Move from scale patterns to triad voicings, then apply both in real-song jam sessions.
Visualize major, minor, pentatonic, modal, and altered scales. Intervals or note names — your choice.
Master every triad shape — major, minor, augmented, diminished — anywhere on the neck. Hear them played back.
Pick a backing track. The fretboard highlights the right scale as each chord changes — in sync with a YouTube backing track.
JamSense
Pick a Quick Preset, hit play, and watch the fretboard automatically switch scales with every chord change — timed precisely to the backing track.
