About Solo - Fretboard Visualization

Solo is the ultimate practice App for mastering fretboard visualization, designed by world renowned guitarists Tom Quayle and David Beebee. Four powerful fretboard trainers allow you to work intuitively on each aspect of the visualization process; learning note names, memorising interval shapes, outlining chord changes, and practicing scales. Solo asks you to find intervallic functions against one root note, chord symbol or scale at a time, listens to the notes you play, and doesn’t move on until you’ve correctly found each note by its intervallic function in the specified order. Practice with Solo and finally learn your note names, master interval shapes, confidently play through chord changes and break out of scale boxes with intervallic functions. Start transforming your playing and confidence on the fretboard today! NOTE TRAINER The Note Trainer is perfect for beginner and intermediate players getting to grips with note names on the neck - the foundation of solid fretboard knowledge. ‣ Solo shows you random root notes to find and listens, waiting for you to get it correct. ‣ Slide on the interactive fretboards for helpful diagrams and to study alternative options. Choose from 6 string guitar (standard and 4ths tuning), 7 string guitar, 4 string bass & 5 string bass. ‣ Optional practice suggestions offer challenging ways to limit and test yourself. ‣ Duration based workouts allow you to craft the perfect practice session. INTERVAL TRAINER The Interval Trainer will help players at all levels work on interval shapes with intervallic functions - the key to unlocking true freedom on the fretboard. ‣ Choose any combination of intervallic functions to practice. ‣ Create custom interval groups or choose the intervals for ANY chord type or scale. ‣ The Interval Trainer will randomise your chosen intervals and ask you to find them against either a fixed or random root note. ‣ Slide on the interactive fretboards for helpful diagrams, showing you where all of the interval shapes are across the neck, and to study alternative options. Choose from 6 string guitar (standard and 4ths tuning), 7 string guitar, 4 string bass & 5 string bass. ‣ Duration based workouts allow you to craft the perfect practice session. CHANGES TRAINER In the Changes Trainer you find intervallic functions, using single notes to outline different chord types or sets of chord changes, a key skill for learning to improvise through chord changes. ‣ Practice outlining intervallic functions through over 100 common chord progressions and single chord exercises. ‣ 50 intervallic function levels.

What Solo - Fretboard Visualization Is Used For

Solo - Fretboard Visualization appears to be a practice app for guitar and bass players who want to improve fretboard knowledge. Based on the metadata, it focuses on helping users learn note names, interval shapes, chord changes, and scale patterns through interactive trainers rather than through general music playback or recording.

The app may be especially useful for structured practice sessions on a phone, since it includes workout-style exercises and interactive fretboards. The listed audio-recording permission suggests it can listen to notes the player plays, which fits the described training flow where the app checks answers and waits for the correct note or interval. Network access may be used for app features, updates, or connected content, while the keep-awake and startup permissions suggest it can support uninterrupted practice sessions.

This app seems aimed at players who want a more deliberate way to study the neck across different instruments, including 6-string guitar, 7-string guitar, and bass. It looks like a focused learning tool for beginners building note recognition and for more experienced players refining interval-based fretboard understanding.
