Modulation Master
Every road from one key, or one chord, to another.
Modulate
Arrows follow Stephen Mugglin’s progression map for major keys and a matching map for minor keys built from the common minor progressions.
Where each route comes from
Routes draw on Bruni, de Fossa, Aguado, Pelzer, Mazanek, Mortensen, Grayson, the Rule of the Octave, Bach’s chorales, jazz practice, Stephen Mugglin’s progression map and the guitar methods of Nava, Carulli and Kníže.
What it is
Most players know one or two ways to change key, and they lean on them until they wear thin. Modulation Master opens up the whole map. Give it a starting chord and a destination, and it lays out the routes you can take: pivot chords, common tones, chromatic slides, sequences and the moves that figured-bass, classical guitar and jazz players have relied on for centuries.
It’s built on the same harmonic engine behind The Octave Lab, the Chorale Generator, Photoplayer and Superimposition Lab, so every suggestion comes from real practice, not guesswork.
What it does
- Finds the possible paths from any starting chord to any destination chord
- Covers routes from figured bass and the Rule of the Octave, classical guitar method books and jazz harmony
- Shows each route step by step, so you learn why it works, not just that it works
- Lets you compare short and long paths: get there fast, or take the scenic route
- Export routes as MIDI and see chord shapes on the guitar fretboard
Who it’s for
Songwriters stuck in one key. Producers who want a drop or a bridge that actually lifts. Players working through theory who want to hear it, not just read it.
