The Woodshed

Where the hours go in.

Two ways to learn the changes — a practice game and a practice room — both built for teachers and students of jazz harmony.

Two educational products. One theory engine.

Blues Prince Media's jazz education tools for teachers and students who need the changes to stick — not just the scales.

The Game

Run the Changes

Guide-tone drilling a student will actually choose to do. You are a note on real music paper; every barline is a door; the golden doors are the 3rd and the 7th of the chord that's coming.

The Practice Room Alpha

Shed the Changes

The academic side. Playable jazz standards, transposition to any key, a rhythm section that swings, and guide-tone overlays that show you the harmony while you work through it.

Both run on THIRI

Most music software thinks in piano keys, so it cannot tell E♯ from F. THIRI is a deterministic music-theory engine that keeps every chord spelling honest. See it at thiri.ai or build on it at build.thiri.ai.
