Every thing should be pretty easy !

Let's begin by the Main Window. It consists of three panels, each panel showing the guitar neck, the tuning menu, the tonality box, the degrees grid.

First panel shows Scales, the second one shows Chords, and the third shows Diatonic scales or how to play scales with chords !
