Intervals are measured in semitones in 12-tone equal temperament, with A4 = 440 Hz. Each round picks a random root inside a comfortable range, so the same interval does not always sound from the same pitch. Notes are synthesised locally with the Web Audio API — no audio files, microphone or network access. Changing the level starts a new round but keeps your score; changing the direction replays the current interval the other way.
