By learning the five CAGED patterns, any diatonic scale or mode can be played by simply transposing the shape to the correct position on the fretboard. If one knows the "C" shape for C major (which occurs in the open position), then one can play the same shape in F major simply by moving the hands up to the fifth fret position and playing the same pattern.

Several tunings and scales are implemented here. The main feature needing some explanation is the tritonic filter, which filters the scale down to its first, third, and fifth notes, so that the CAGED shape is more easily recognized.
