"title": "Zoom Deep Inside of the Fretboard",
"body": "Our vision, as guitarists, is typically related around large scale shapes that run up and down the neck and large arpeggios that run up and down the fretboard. This can help take us to a certain point, where we tend to plateau. Sølo offers a different way of seeing the fretboard. It offers a zoomed in view of the fretboard that is built on a deeper knowledge of the fretboard that focuses on note recognition, i.e. knowing the exact note of every fret in every position, and then all the corresponding chord tones, arpeggios and scalar shapes around any given note. I have been using it for a few days now and it forces me to slow down and it forces me to see the fretboard in a more active way that uses up more mental resources which seems harder. Sølo forces us to use or develop different muscles, and it is a mental workout. For me, it’s even more of a mental workout because I usually keep my guitar tuned down to Eb standard, so I have to play everything one fret sharper than it would otherwise appear on my fretboard. I am thinking about returning my guitar to E standard as that makes sense but I wanted to get started right away. Now I am getting used to the app, and I definitely don’t recommend using non standard tunings because it is unnecessary complications for the learning process. This app works well for bass players and different stringed instruments as you can adjust the settings of the app to match your instrument. Overall, it is an excellent app and a unique tool for developing a deeper understanding and knowledge about your fretboard.",

"title": "The tool I was looking for to understand the fretboard",
"body": "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.",

"title": "Would love sheet music training for note names",
"body": "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",

"title": "The FIRST beneficial guitar APP!! Open the gate of music!",
"body": "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!",

"body": "I’m a couple days in on a self structured practice routine (one of the good things and hard things about this app, you have freedom and responsibility in deciding how you’ll use it.) Having learned scale shapes, chord shapes, caged system, etc. There has always been something missing, in the way my brain takes that information and understands how to use it in context, and then project it on the fretboard. This app is already bringing it all together. I’d say it has to be an invaluable piece of learning for any guitarist from now on. And, it’s reasonably priced, No monthly membership. Awesome. Great job fellas!",

"notes": "1.1 release notes New Features *Voice Leading. *Instrument selection. *Transposing support for sax, trumpet etc. *Improved level updates - Chord Scale (Randomised Starting Chord Tone). Solo - Fretboard Visualization 1.1.0 Voice Leading When randomising a level you can now also turn on intelligent 'voice leading'. This will automatically choose the nearest chord tone for the first note of the next chord. This connects chord changes together, resulting in a more musical and real world way of practising. Instrument Selection This allows you to select the instrument you are using and optimise Solo's note recognition. Transposing Support. Since launching last month we've discovered Solo being used enthusiastically by non-guitarists and had many requests to support transposing instruments. Our new instrument selection allows Eb and Bb horns to practise with Solo. Improved Level Updates Chord Scale (Randomised Starting Degree) has been updated to the more useful Chord Scale (Randomised Starting Chord Tone). Thanks! We've been blown away by the response to Solo, and we're thrilled to see so many people enjoy practising! We also really appreciate the feedback and feature requests, rest assured we're working hard to make Solo bigger and better! Stay tuned to our website/blog/socials and Tom and David's personal social media profiles for the latest updates and what's coming next. Cheers, Tom , Beebee, Mike"

"notes": "We're super excited to bring you Solo v2! For this new version we've re-imagined what the experience of Solo should be, offering a much more complete learning and practice tool for players at ALL levels. To achieve this new vision we've included: - ‣An updated, intuitive design with two powerful new trainers, making Solo MUCH more accessible and useful for beginner and intermediate players. ‣The Note Trainer allows you to work on finding notes names and basic root notes with practice suggestions to guide your workouts. Solo challenges you to find randomised root notes on the neck and confirms when the chosen note has been played. ‣The Interval Trainer allows you to work on finding Intervallic Function shapes, the key to unlocking true freedom on the fretboard. Select a single interval to work with or create any combination of intervals to find against either a fixed or randomised root note on the neck. ‣Both new trainers feature optional onscreen interactive fretboards that react to what you play, enhancing the learning experience during your workouts. Solo includes fretboards for 6 and 7 string guitars, 4 and 5 string bass and even supports Tom Quayle's own 4ths tuning. ‣Other new features include: Duration based workouts, allowing you to set timers for your practice sessions in the Note, Interval and Scale trainers. ‣The Changes Trainer now offers truly random transposition upon repeat. For example, select one of the common chord progressions (such as a Major II-V-I) or single chord types and Solo can now randomly choose a new key (or root note for single chord types) every time you complete the progession. ‣We’ve included 50 new jazz standards, new changes trainer levels plus new exercise progressions. ‣Solo also now remembers the last thing you were doing in each trainer, so you can continue practicing right where you left off."
