Interface DrillCardProps

For a question answered by playing (question.playAnswer): shown in place of the answer buttons — a panel that listens to the instrument and calls onAnswer with what was played and whether it was right. Without it, the question is answered by choosing, like any other

Anything to show under the question — a hint, a replay button

The round's place, from 0

Supplies the notation engine for the staff

The names answers are shown by: intervals, chords, scales and keys

For a question answered by playing, once it is: how the notes to play were played, as note styles for the staff — a colour per note and the note played in a wrong one's place — as a graded take's are drawn

A choice was made — or, from answerArea, an answer played, with whether it was right

Called when the staff fails to draw or the sound fails to start

End the drill early, keeping what was answered (useDrill's finish); the Finish button shows when given

Move on

Told when the card starts and stops sounding notes — the question, its starting note — so a microphone listening for the answer can wait for the card to fall quiet

The round being asked

Recorded samples to play the question with — a piano, say — instead of the built-in voice; the question's notes are downloaded as it appears. The SDK ships none: you choose the host, and that set's licence applies

Play the question once a choice is made, with a button to hear it again (default: true). A question asked by ear (question.byEar) is played as it appears — after its reference note, when it has one — with its staff hidden until it is answered; with sound off, or where the browser has no Web Audio, it shows its staff like any other

How the drill has gone so far (useDrill's summary): given, the card shows the running score and how far through the drill it is
