Landing page captured for the 2026-09-12 issue.

Field notes

The interface assigns note ranges to letter and number keys, with separate mappings for low, middle, and high registers; pressing multiple keys produces chords, while Space supplies sustain. A 90 BPM metronome and basic record, replay, and erase controls support short practice sessions. The page also exposes solfège and international naming, plus student group-code and teacher-email account paths for saving progress.
