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.

The tool I was looking for to understand the fretboard
10/04/2025

Sickbar
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.

Tom is a great guitarist and instructor. I have several of his courses from his website. I saw he had came out with this app. And just knew if he had anything in putting it together it would be awesome. Firstly this is the way to learn guitar, sadly it took 12 years of playing for this stuff to start showing up in my playing. Will definitely hit a wall in progress with playing if not thinking of target notes and the intervallic structure of chords/scales. It’s crazy I’ve been thinking of a way to practice this stuff in this way like flash cards or something! Guess that’s why I’m writing the review and Tom made the app! But extremely grateful for this contribution to the art and if a lot of young guys start using and learning this way it will change music!

Great app, but just a suggestion.

Louie plays guitar!
This is a great app, I love the purpose behind it. I feel with time it will greatly help me to become a better guitar player. However, I would caution saying this app could be suited for beginners. Personally in my experience most beginners have zero theory knowledge. And even for those beginners who are learning theory, I feel this app could be a bit advanced and maybe even a little discouraging for them. Beginning players usually benefit from song audio references, scale and chord diagrams and what not, and I feel this app has a different focus in mind. I would suggest aiming this app at the intermediate to advanced player in terms of theory, not playability. Some people may get the wrong idea if they don’t read all of the literature from the website. Other than that, keep up the great work!

Over many years i have spent a lot of cash on music books, videos, cd’s, incompetent teaching methods, name it iv’e probably owned it. You could say that i am a well rounded guitar manipulator, as the saying goes “a player of many, a master of none”. This app is exactly what it says, it is a help- mate. Meaning, no matter what curriculum you choose it all comes down to putting your time in.This app will give you some very powerful platforms to work from, its up to you to perform those platforms. I would honestly and will, tell my friends about this app, because it has substance with only as much difficulty to challenge you to put your time in. For me, I have over the years been very fortunate to be in bands as a vocalist, not having to play guitar all the time. But really, within those bands I was left behind as far as guitar abilities. So, my point is, yes get this app, but don’t forget you must put in the time. You cannot avoid it, if you wish to fulfill your dreams, do your time.I wish you all of the fortune out there to get. GodblessAnd to those who created this app, job well done, i will use this app as a reference for work, and also when i practice. I practice no less than 3 hours a day, and sometimes up and to 8 hours. GoodluckEveryoneBurley Lerux
