Question 2. Modes — the seven modes under the chords of a key
Drag the modes sideways (or use the arrows). The mode under the first numeral is the key's
mode; each numeral is the chord on that degree, and the mode beneath it is the mode that starts there.
Turn the purple chord at the top up or down to pick the key note: the other chords follow.
