Audio plays only when you click — no autoplay. Intervals play the root then the second note; chords arpeggiate up, then play together.
Daily Ear Riddle
One interval a day, the same for every player worldwide. Press play, name what you hear — after a miss you learn whether the answer is wider or narrower, so a careful ear (or careful bisection) always gets there. Part of the 30 Days of Ear Riddles challenge.
