Solo is a comprehensive practice application designed to help guitarists and bassists master fretboard visualization. Developed by renowned guitarists Tom Quayle and David Beebee, this app provides four powerful training modules that target essential aspects of fretboard mastery. Users can work on learning note names, memorizing interval shapes, outlining chord changes, and practicing scales through interactive exercises.

The app's unique approach involves asking users to find intervallic functions against specific root notes, chords, or scales while listening to their input. This ensures proper understanding before progressing. With support for various string configurations including 6-string guitars, 7-string guitars, and 4/5-string basses, Solo offers versatile practice options for musicians at all levels. Whether you're a beginner learning basic notes or an advanced player working on complex melodic structures, Solo helps transform your playing and boost confidence on the fretboard.

Solo stands out with its four specialized training modules: Note Trainer, Interval Trainer, Changes Trainer, and Scale Trainer. The Note Trainer helps beginners and intermediates learn note names across the fretboard using interactive diagrams and duration-based workouts. Users can choose from different tuning options and receive practice suggestions to challenge themselves.

The Interval Trainer focuses on mastering interval shapes through customizable practice sessions. Musicians can select specific intervals, create custom groups, or practice intervals for any chord type or scale. The app's intelligent mapping system listens to user input and provides alternative options through interactive fretboards. Advanced players will appreciate the Changes Trainer, which helps outline chord progressions and single-chord exercises using intervallic functions.

The Scale Trainer offers over 50 scales and modes with powerful workout options. Users can break out of traditional scale boxes and develop deeper understanding of scale construction across the fretboard. All trainers feature duration-based workouts, transposition options, and voice leading practice, making Solo an indispensable tool for serious musicians looking to elevate their skills.

Moreover, the app's dedication to copyright authenticity means that all the educational material is legitimate and respects intellectual property rights. Users can trust that they are learning from accurate and legally sound content, which enhances their learning journey without legal concerns.

Audio quality is paramount when training one's ear and practicing musical techniques. Solo - Fretboard Visualization takes this aspect seriously by offering high-quality audio options that allow users to discern the nuances of different notes, intervals, and scales.

The app listens to the notes played by the user and provides feedback on their accuracy. This interactive feature requires superior audio processing to ensure that each input is captured precisely. By delivering clear and crisp audio feedback, learners can fine-tune their understanding of the fretboard with confidence.

In addition to standard audio playback, Solo also supports various tuning options, including standard and fourths tuning for guitars, as well as accommodations for 4-string basses up to 7-string guitars.
