Practice tools built to back up the teaching
Three apps, each built to drill one part of real musicianship — the fretboard, the rhythm, the ear.
Solo
The ultimate practice app for mastering fretboard visualization, built with David Beebee.
Four fretboard trainers work on note names, interval shapes, chord changes, and scales — each one built around intervallic functions rather than shapes to memorize. Solo asks you to find each function against a chosen root note, chord, or scale, listens for the notes you play, and won’t move on until you’ve found every one correctly and in order, so visualization becomes a skill you build by playing rather than a pattern you memorize.
Metric Flow
Supercharge your rhythm skills and build your rhythmic vocabulary.
Metric Flow generates fresh one-bar rhythms on demand — in straight time, odd meters, or polymetric overlays like 7/8 over 4/4 — and shows each one as standard notation or as an animated Timeline View of pulsing dots, so the rhythm is felt as much as read. Tap any pattern to reshuffle it, shift it forward in 16th notes, or work through every permutation across the bar.
Resolve
From thinking to instinct.
Resolve trains a different kind of ear — not labeling chords, but responding to them. The app generates constantly shifting harmonic material at an adjustable complexity, from simple, stable sounds up to genuinely dissonant ones, building a direct reflex between what you hear and where your hands go, with no theory analysis in between. A companion video course from Tom and David Beebee teaches the reactive method step by step alongside the app.
