Interactive jazz études — see it, flip it, hear it.
Learn the shapes that make jazz work — modes on the guitar neck, chords moving through a scale on neck and keyboard. Each study is a living chart: pick any key, flip between hearings, step through the motion, and tap any note to hear it.
One convention ties it all together: color shows what a note does in the current key. The root is always red, the third always blue, the seventh always amber — so a shape you learn in one study is instantly readable in every other.

Studies
Every mode is a guitar pentatonic box you already know, plus two notes. An interactive fretboard map in every key — see it, flip it, hear it.
Four-note chords walk through a scale one smooth voice-leading move at a time — on a guitar neck and a keyboard. Any key, five cycles, sound included.
