Whats new in Solo v2.1.0

6 things about Solo - Fretboard Visualization

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. ‣ Practice outlining intervallic functions through over 100 common chord progressions and single chord exercises.

If I could give it 20 stars I would!!

I’ve been studying triads, chords, harmony, etc for years but it never fully clicked the way I always wanted. Then I got this app, and within ONE DAY it all started finally clicking. The way this makes you automatically start to visualize the different intervals, scales, triads, etc is a complete game changer. Why did it take me so long to realize how easy it is to memorize the interval locations? Seriously thank you for creating this app, it’s a masterpiece! And ps: the YouTube videos help you get even more out of it. Solo user for life!

Not Worth 14.99

I respect the amount of work that went into writing this app. And yes Intervals are a great way to learn the fretboard. However, the app is not close to being worth what they are charging. All it does is intervals. It does not use or recognize notes. There is an entire channel dedicated just to figuring out how to use the app. Many other apps for less than half the price of this one and are far better in terms of learning the fretboard. I would get a refund if I could after purchasing and realizing it does nothing with notes.

This is a great app

I’m not sure why it’s not possible for people to add their own tunes or chord changes to the app. i know that i have iReal that i could use, but i like the “game” feel of this app as well as the way it forces me to think in intervals & scale degrees & the like
