Your keyboard, your songs, no subscription.
MIDI hears every note but it cannot see your body. Prop your phone up and film one minute, then watch it against these five checks. No video is recorded by the app.
Camera angle: torso, forearms, wrists and keys all in frame.
Remember: recurring pain or uncertainty means show a human teacher.
Want a new song? Ask Claude to curate it into the library, that is the pipeline.
Every one of these links to the run that earned it. Arcade stats are fun and say so, they are never claims about your playing.
Press any key on your piano, or play C4 below. We will tell you exactly which key arrived.
Where are you starting? Either way, we will hear four bars together.
Every key you press lights up below, with its name. Good first test that your keyboard is talking.
One thing at a time, chosen from what you have actually played. Teacher Loop v1 takes you to playing a pop song from a lead sheet.
The stuff a teacher would explain, in order. Each lesson ends with a drill you answer on the piano. Finish one to unlock the next.
Four clicks count you in, the pattern plays once, four more clicks, then YOU tap it back on any piano key. Three clean rounds and the patterns get trickier.
I play a phrase from one of your songs. You play it back. A wrong note restarts the phrase. Five clean echoes in a row and the phrases get longer.
A bar drops onto the line at a steady beat. Press ANY key exactly when it lands. Eight taps, we store the median offset and use it when scoring your timing.
No judgement zone. Nothing here is scored, ever. Pick a loop, start the backing, and make noise over it: bright filled-dot keys are the CURRENT chord's tones, outlined-dot keys are safe scale tones.
Every major and natural-minor scale, standard fingering, as trainer drills. A key is passed when the trainer has taken BOTH halves (up and down) to full tempo. Click a key to train it.
Recorded runs: your real sound (mic) plus the exact keys you played (MIDI), for honest A/B review. Audio is never scored, mic gain lies. The shelf keeps the newest 20; older takes fall off.
Your piano's action is not uniform and neither is your hand. Play the asked key at the asked strength; the app learns YOUR soft, medium and strong per register, and all dynamics feedback maps through that instead of raw numbers.
