Chord dictionary & voice-leading assistant
Every voicing in this course for all twelve roots: shells, triads, drop-2, drop-3 and rootless shapes, plus a tool that picks smooth voice-leading through any progression you type.

Voice-leading assistant
Type a progression (chord symbols separated by spaces or bars) and the assistant picks, for each chord, the voicing that moves the fewest semitones from the previous one, staying on one string set where it can.

How the shapes were made
Every diagram comes from the course's theory engine, not from a hand-typed chart. For each chord symbol the engine spells the chord, builds the close-position inversions, applies the drop-2 or drop-3 transformation, and then solves for the lowest playable fret positions on each string set (a hand span of five frets or less). An automated test plays every one of the 8,000-plus shapes back through the fretboard model and checks that the sounding notes are exactly the chord's notes. The same data feeds the voicing lessons in Modules 4 and 8.
