Tone Logic generates real, playable progressions and shows you exactly where they live on the neck — so practice stops being repetition and starts being making music.
You learned the chords. You learned some songs. And then… nothing. The moment the chords stop being handed to you, you freeze. You can't hear what comes next, you can't write your own thing, and YouTube is a thousand fragments that never join up.
Lessons are expensive. Theory feels like homework. And you didn't pick up a guitar to do homework.
Tone Logic hands you a real progression in any key, shows you every shape in positions your hand can actually reach, and lets you loop it, drill it, and build on it until your hands know the way without being told. You absorb the why by playing, never by reading.
Pick a key, a mode, how many chords. Get a real, named progression you can play right now — then add colour as you grow: borrowed chords, 7ths, extended voicings from a subtle shimmer to full jazz.
Every chord as a fretboard you can actually read at arm's length, multiple neck positions, and a metronome that follows your progression's own bars — the patient practice room that meets you where you are.
The deeper dive: sit inside the relationship between two chords in a key — root to any degree — and loop it until the connection is yours. This is where exercises quietly turn into playing.
Real blues patterns with styles and turnarounds, because the blues is many ways to play few chords — and every one of them teaches you the neck.
Your progression, your rules: up to 32 bars, split bars, borrowed colour, remix and rework until it's a piece — then practise it like any other.
The key changes on the clock. You adapt, find the shapes, stay present. The board teaches you where each key lives on the neck while you wait — nobody else does this.
Pick a key, scale and starting string; see it laid across the neck with the parent key alongside, so you learn the relationship, not just the dots. Pentatonics to full modes, the foundation laid in the right order.
Every play mode opens onto a full-neck landscape board — the whole fretboard, your bars along the top, the shapes where they really live.
Fun and playable beats clever and complex.
Theory arrives through your hands, never as homework.
Each of the 765 chord shapes inside has been physically played and graded by hand, one by one, 1 to 5, for how it really sits under the fingers. Nothing asks for a stretch a real hand can't make.
Chords, scales and the neck in one place that shows how they relate.
I'm from the world of building and architecture. I taught myself guitar the slow way — years of barely moving forward, with nobody to tell me what I was missing — and then work took over and the guitar went away for far too long. When I finally came back to it, the penny dropped about keys, and which chords belong together, and I remember thinking: something that just handed me real progressions would have saved me years. So I built it.
Every one of the 765 chord shapes inside has been played and graded by my own hands, and along the way I've helped a handful of stuck players out of the same place I was. The funny thing is, I think the clarity came from the patience — going slowly is how I found the simpler way through. I'm still learning; anyone honest is. But the way out of stuck? That, I know.
