Scale and chords are shown in positions or all notes, covering the fretboard in any key. Notes can be displayed showing the letter name, interval and fingering. Chords and scales can be played at the same time allowing you to hear how a scale sounds played over a chord. Play scales/chords by swiping strings; direction determines low/high or high/low playback.

Practice scales using the scale playback loop. Play along with one octave or the full scale position. Playback speed is adjustable allowing you to start slow and speed up as you master each scale position.

Learn scales by playing along with five patterns that cover the fretboard for each scale. Scale positions correspond to the popular CAGED system. The CAGED system chord shape for the current position of a scale is displayed to help you learn and remember scale positions in any key.

Rosemarie and Chuck

This is a great application. Don’t waste your time with the free version that comes with adds. Spend the money on this app, I promise, you will love it. It is the best app I found to learn the different scales and to use with backing tracks. It is the perfect reference guide to help you visualize the scales, the shapes and identify where the root notes are in a glance. Buy this app, it’s what I was looking for and it’s great!



The app shows with great clarity and simplicity the positions of the scales and chords across the fretboard and offers many tools to understand and visualize.
I’ll make a quick point about service in which I could not get sound from the app, I emailed about it and got an answer and solution within the hour.

Beautiful design


This app has continued to add useful features over the years. It is the best such tool I have found, and the latest improvements have taken it into a whole new league. This design is beautiful and so simple to use for fretboard and harmony study. At three bucks, I don't know of a better deal. Buy it.
