ScaleViz was designed to burn the Major, Minor and Dominant, Chord, Arpeggio, Pentatonic and Scale Modes into your mind, so that they become part of you, visualising the various patterns will become second nature and in turn your brain will transfer the information to your fingers as muscle memory.

The Shape Trainer shows you visually how Fretboard mastery works, you will not even have to think to link the chords, arpeggios and scales together, you will see it happen right in front of your eyes simply by browsing the virtual guitar fretboard…

You will see how the Major, Minor and Blues Major pentatonic scales fit together. How the relative Minor chords and the Major, Minor and Dominant arpeggios fit inside the Ionian, Mixolydian and Aeolian Scale Modes, which all wrap around the Pentatonic's,  and how all of these sit on top of Octave patterns and the CAGED system.

Best of all… All of this will happen without you even realising, as ScaleViz shows you how all of these patterns combine to create a unique map of your guitar fretboard, VISUALLY!

ScaleViz gives discount for educational facilities and supports family sharing.

ScaleViz has been described as one of the most in-depth guitar guides available for the iPhone and now this amazing app is truly universal, after 5 years in development and a life times study, ScaleViz is now available for iPad too, and browsing through the Virtual Guitar Fretboard for just a few minutes a day will save you hundreds, if not thousands of hours of study, guaranteed.

Mastery of ScaleViz will give you the knowledge you need to master your fretboard, and immediately know which notes to use, you will learn the relationships between chords and see how they are built visually, how modes work, how Major, Minor and Dominant chords are related to each other and much, much more…

Ratings and Reviews

Very helpful applying music theory in a practical and logical manner to the guitar neck. Developer was very quickly and thoroughly responsive to my pre-purchase questions, and after purchasing it, I have had three 'a-ha' moments in the first week. That's a pretty inexpensive return on investment, especially if you look at it like a lesson.

What I like most so far about the app is that, unlike many chart-oriented graphical displays of theory concepts, it displays one shape/pattern at a time instead of a neck diagram that has 80% of the frets filled in with dots to maximize the info in one diagram. That's OK if you can see patterns within patterns (seems to work for most people, but not me).

There is a lot of great material available on the 'Web, and this is helping me utilize other resources more effectively. Everyone learns in their own way, but this has revealed some concepts that were eluding me.

Developer Response

Hi there 2-cymballed monkey that is so great to hear and thank you for taking the time to write this review, i'm so glad you had that a-ha moment that is exactly what I was going for and I agree, it is hard to see what is going on when your screen is cluttered, which is exactly why ScaleViz was developed in the complete opposite direction, and I am pleased this concept is working, thank you very much for supporting ScaleViz. All the best Shane.
