Field notes
The visible preview asks learners to enter a triad’s notes, separate them with spaces or commas, and use # or b for accidentals; the page says answers are checked without an account. It lists 828 generated spelling examples and describes a counterpoint room with notation, playback, and feedback across 180 combinations, alongside distinct learner-practice and teacher-classroom paths.
