The Ear Training Lab

Changing the vocal range will restart the game.

A note is played. Your task is to sing that note back as accurately as possible.

After a countdown you'll have 4 seconds to sustain the note. The tuner dial comes alive and shows your pitch in real time. The needle turns green when you are within 5 cents — that's very accurate!

The game clips the beginning and end of your singing (to ignore pitch attack and decay) and takes the median pitch of the middle portion to score you.

Cents are hundredths of a semitone. ±10¢ is excellent. ±40¢ is noticeably flat or sharp.

Use ⚙️ Settings to change vocal range if the notes are too high or too low for you.

Pause pauses countdowns — it cannot interrupt an active note or singing window.
