Positions on the neck
The positions follow the CAGED system: the neck splits into 5 regions, each with the shape of an open chord (C, A, G, E and D) moved to F sharp. In each shape the arpeggio goes from root to root: two octaves in the E and G shapes (root on the 6th string), one octave in the C and A shapes (root on the 5th) and in the D shape (root on the 4th).
The faded notes around a position are chord tones too: use them to extend the arpeggio down or up.
Use Degrees to see the role of each note (1 is the root) and Listen to hear the selected position going up and down, at the tempo you want. With the whole neck, Listen plays the arpeggio from the lowest root.
