Welcome to the tuning challenge! You'll hear two tones. Your job is to tune them to the correct interval indicated by the upper display. Once you have achieved the correct interval, you can submit it by pressing the check mark down below. Then that box will reveal how close you were (how many cents apart you managed to tune the notes).

Some sound settings are available if you want to change up the tones a bit.

Please note that this exercise will expect you to tune intervals to twelve-tone equal temperament by default. Therefore; some things might sound slightly better out of tune than in tune.
