Solo - Fretboard Visualization
🇯🇵 JP LocalizedScreenshots
Description
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. Go from simple chord tones to complex melodic structures and scales. ‣ Solo intelligently maps out the correct intervals over each chord and listens for you to play each intervallic function in the specified order. ‣ Powerful workout options provide almost limitless ways to challenge yourself. ‣ Transpose the key of any progression or exercise. ‣ Choose to randomly transpose the progression (or single chord exercise) each time it repeats. ‣ Work on voice leading chord tones through single note lines. SCALE TRAINER The Scale Trainer contains a vast array of scales and powerful workout options, allowing you to finally break out of the box and develop a much deeper understanding of how scales are constructed on the fretboard. ‣ Practice finding scales on the fretboard using intervallic functions. ‣ Over 50+ Scales and modes. ‣ Powerful workout options provide almost limitless ways to challenge yourself. ‣ Melodic sequence options let you focus on starting from any chord tone within the scale. ‣ Duration based workouts allow you to craft the perfect practice session.

Essential for interval visualization, can’t wait for what they’re gonna bring to this app in future updates.
Hi! I love the app, its a great way to memorize the note names. I have one ask for the app: can you include sheet music notation for the note trainer? I am trying to learn how to read so it would be helpful. Even for people who don't care to read, an option to add an octave marker (E3 vs E4) would be helpful, since that can help you figure out which E's are the same and which are different, for example. I think having a note marked on sheet music is the best option as it is very visual, but let me know what you think! Really like the app otherwise, let me know what you think
Improved my fretboard knowledge and my soloing abilities. Much easier now to flow to the right next note.
For my money the best fretboard/interval training app available.
I thought this was to help learn the fretboard without holding the guitar or even requiring a guitar. I thought this was to learn finger placements by having a virtual fretboard.
For what it costs, I was expecting more. Some things that feel like no brainers to me: showing the note on the treble clef, and showing the fretboard for scales. Something that would be nice given the technology is giving a reference note and then asking to find another note (interval ear training). Also, a way to gamify it (e.g. streaks, quests) would be nice to have a sense of reward. Overall a decent practice tool to start learning the fretboard, but given that it's paid it could be a lot more.
This is a wonderful app to train the intervalic functions and for beginners learning the notes and relations on the fretboard
This is a great tool to hone your chops and ears over changes. A great daily practice tool
GOT TO SAY that the fact that I know in a second where and what I’m doing on which notes feels incredible, and it’s NOT TRIVIAL AT ALL. I recall a few months ago when I was frustrated, and I didn’t know how to memorize the fretboard, let alone understand why triads appear the way they do or how to form one on the fly. The only thing that kept me going was the fact that obviously others know it, and that I’m not an idiot, but I couldn’t figure out how to train myself. SOLO totally paid out for that. Add to that the real power of solo understanding intervals, and WOW, I think this was the single most powerful and breakthrough improvement I had. One thing I hope they add is statistics to see how fast you find whatever notes the app asks you to. THat would help visualize the improvement.
Incredible app! My knowledge and improvisational skills have soared! Thank you!
mode "Changes" doesn't work... Intervals detects my notes but changes doesn't
this is exactly the one I was looking for... it provides a large convenience and removes unnecessary labors!! nice work Tom!!
