Use your own acoustic piano or a USB MIDI keyboard. Notes move toward a play line and wait. This page stays quiet so the microphone is not confused, and only moves forward when you play the right pitch. Wrong notes pause the song instead of skipping ahead.
First, play C4, E4, and G4 on your piano
C4 is middle C. Then play E4 and G4 to the right.
Tap the big button, allow the microphone, then play those three notes on your real piano.
This page stays silent while it listens so the microphone does not hear the computer.
These three notes are next. Tap the button above, then play them on your piano.
Microphone calibration, MIDI, silent pages, and what this tool does not score.
Play a few notes is a hearing check, not Bluetooth pairing. The browser uses the device microphone. You play C, E, and G. The page checks that the mic is allowed, the piano is loud enough, and the pitch is not an octave off. After that, each key strike is an onset plus a pitch guess.
A USB MIDI keyboard sends the exact key you pressed. Chrome and Edge handle this well. There is no room noise and right versus wrong is almost certain. Safari and many iPads do not support Web MIDI, so use the microphone there.
The computer speaker can fool the microphone. This page does not play piano sounds while it is listening. Mute other tabs, and use headphones on the computer if you still need sound from something else.
The note at the play line waits until the matching pitch arrives. A wrong pitch flashes and the song stays put. There is no metronome grade, no two-hand scoring, and no chord detection in this version.
The song list matches Color Piano: traditional nursery and folk melodies such as Hot Cross Buns and Twinkle Twinkle. No copyrighted pop songs.
Sit the tablet or laptop near the piano, play a little louder, and run the C, E, G check again. Acoustic pianos are easier in a quiet room. Large rooms and heavy sustain make pitch guesses harder.
Next labs in this group. Everything runs in your browser.
It is a free wait-mode teacher for the same public-domain songs as Color Piano, except you play them on a real instrument. Upcoming notes move toward a play line on the left. You play the front note on an acoustic piano through the microphone, or on a USB MIDI keyboard. When the heard pitch matches, the song moves forward. When it does not, the page pauses, shows the pitch it heard, and keeps waiting. Nothing is uploaded. The browser listens on your device only.
Tapping colors on a screen teaches the tune, but it does not train fingers on a real keyboard. Wait mode keeps the next note at the play line while your hands stay on your own piano. You can slow down, repeat a note, and fix a miss without the song running away. That is the loop used in early piano apps: show the note, wait, pause on mistakes, then continue. It is a calm practice habit for beginners and parents sitting together.
No. Playing C, E, and G is a microphone hearing check. The browser is not pairing with the piano. It only confirms the mic works, the piano is loud enough from this spot, and the pitch tracker is not an octave off. MIDI over USB is a separate, more accurate path for digital pianos.
Use MIDI when your digital piano or keyboard can connect by USB and your browser supports Web MIDI, usually Chrome or Edge on a computer. Use the microphone for an acoustic piano, or when MIDI is not available. MIDI is exact about which key you pressed. The microphone is good enough for one note at a time in a quiet room.
If the computer plays the same notes the piano is playing, the microphone hears both and the tracker gets confused. This page does not play a synth while it listens. Use headphones on the computer if you still want other sound, and keep extra browser tabs muted.
The song does not skip. The page flashes the note it thinks you played and keeps waiting for the note at the line. Play that front note to continue. Repeated notes in a song, such as two C keys in a row, need a fresh key strike each time.
No. Songs are single-note melodies in a two-octave range, C4 to B5. The tool waits for pitch. It does not score timing, chords, or left-hand parts. That keeps v1 honest and usable on a laptop mic.
The microphone path works in mobile Safari after you allow mic access. Web MIDI is weak or missing on many iPads, so a USB digital piano may need a computer browser. Sit the iPad close to the piano and run the C, E, G check before a song.
