Brief Introduction

FretApps: Modes 101 has just been added to the App Store! Here's a brief introduction to the app;

When you open the app you are brought to the wheel. You can select the mode-pair (Module) you wish to study, as well as the key and the Form. The Form denotes the specific string group for the modes, and the precise fingering pattern.

The image above shows the Ionian/Phrygian Module in the Key of C, Form 1 (rooted in the 3rd and 4th strings). Notice that the two modes form a symmetrical pattern when paired together, and that they overlap.

Here the view of the fretboard has been zoomed in by pinch-zooming. Also, the key has been changed to Eb and the note names have been replaced with Roman Numeral scale degrees. 

Tapping either of the mode shapes will cause the mode scale to play, starting from the lowest pitch. The modes will play as ascending and descending scales at a moderate tempo so you can play along on your guitar.
