Solo - Fretboard Visualization

Solo is the ultimate guitar fretboard practice app designed by world-renowned guitarists Tom Quayle and David Beebee. It features four trainers—Note Trainer, Interval Trainer, Changes Trainer, and Scale Trainer—to master note names, interval shapes, chord changes, and scales. The app listens to your playing and won’t move on until you correctly identify the requested intervallic function in the given order, building precise fretboard intuition.

Extras include interactive fretboards with 6-string standard and 4ths tuning, 7-string, 4-string bass, and 5-string bass, duration-based workouts, transpose and randomization options, and voice-leading focus. Suitable for beginners to advanced players, Solo helps you internalize fretboard logic, improvise with confidence, and break out of scale boxes.
