Learn
Watch and listen first — the score and keys light up while Mia plays it for you.
Practice
You play, the app reacts — green means correct, and it patiently waits for you.
Test
A count-in, then play in tempo with fewer hints — your accuracy is recorded.
Best with a MIDI keyboard
Connect a digital piano by USB and open the site in Chrome or Edge — every note you play is checked in real time. No keyboard? You can still learn with the on-screen piano.
How each lesson works
For every exercise: ① Learn — watch and listen. ② Practice — press Start and play; the app waits for you. ③ Test — one count-in measure, then play in tempo. Use any order and skip freely, in every key your instructor assigns.
When you're signed in with your class codes, your completed exercises, practice counts, and Test results are reported to your instructor automatically.
