The right answer, as a code among the choices: a note's name ("F♯"), an
interval (M3), a chord quality (minor), a key (D:major), a scale
(dorian). Show it with labels of your own, or the defaults of

Asked by ear: heard first, and seen once answered. Never for a key signature, which is read
The answers to choose from, shuffled, the right one among them
The question on its staff, as a one-bar MusicXML score to draw
The notes the question is made of, lowest or first first
The note shown
Answered by playing, what to play; null otherwise
Answered by playing on an instrument, not by choosing a name
Whether sounds are heard together or one after another
Asked by ear, the note heard before the question to name it from — the
C at or below it — for a note; null for the rest, and for any question
not asked by ear
What the question sounds like, as MIDI numbers — heard once it is answered, or first when it is asked by ear
A note on the staff to name.
