What is ear training?
Ear training is practice at recognizing music by listening. Learning to hear intervals, the distance between two notes, helps you sing in tune, play songs by ear, and improvise.
Is ToneSlime free?
Yes. Stages 1 through 50 are free to play and replay, and you can start without an account. Stages after 50 are a one-time unlock on your account.
Do I need a piano?
No. ToneSlime has a piano on screen. Tap the keys on a phone or tablet, or click them on a computer. Headphones or speakers help you hear each note clearly.
Do I need to read music?
No. You answer by ear on the piano. A music staff shows the notes as you play, so you can pick up reading along the way.
