A grand piano you can sit at
The Concert Hall is a 3D stage with a playable grand piano on it. The instrument is sampled rather than synthesized, so held notes decay the way a recorded piano does and chords keep their weight instead of turning into a flat electronic pad. Nothing to install, nothing to configure: the hall loads and you play.
How to play it
- Click or tap the keys on the piano itself.
- On a computer keyboard, A W S E D F T G Y H U J is the octave from middle C, and K O L P and the two keys beside them carry on up to F. ← and → shift that layout by whole octaves, ↑ and ↓ transpose a semitone at a time.
- Pedals: Alt or N for sustain, V for the soft pedal, B for the sostenuto.
- Connect a MIDI keyboard from the control bar and play the real thing through the hall's piano.
The camera is part of the instrument
Three views. Orbit hands you the controls: rotate, pan and zoom around the stage. Cinematic takes them back and circles the piano slowly on its own, which is the one to leave running while someone listens. Seat and Play snaps the camera in front of the keyboard and locks rotation and panning so the view stops moving while your hands do. That last one is the practice view, and it is worth choosing deliberately rather than staying in Orbit out of habit.
The music stand and the Professor
Signed-in players get two things more. The tablet on the music stand runs the full sight-reading trainer, with Listen, Wait, Scroll and Free modes, so a score can sit in front of you while you play the piano on stage. And the Professor, the site's coach, comes with you: Name it announces every chord, note, interval and scale the hall sounds, whether you played it or the piano did, and Repeat after me is a spoken call-and-response ear-training game across five levels, from single notes through two-note pairs, short phrases and runs to full chords.
What it is good for, and what it is not
This is an instrument to think at: test a voicing, check a chord you found by ear, work through call-and-response, or simply play when there is no piano in the room. It will not build technique, because a screen has no key weight and no escapement, and no software can fix that. If you want the piano without the stage, the virtual piano is a lighter page, and if you want your playing graded against a score rather than named back to you, that is the job of the AI piano coach.
Questions about the Concert Hall
Do I need an account to play in the Concert Hall?
Not to play. The piano, the pedals, MIDI input and the camera views are open to everyone. Signing in is what adds the Professor overlay and the score on the music stand, and an account is free.
Which computer keys play notes?
Two rows, starting on middle C: A, W, S, E, D, F, T, G, Y, H, U, J for the first octave, then K, O, L, P and the two keys to their right, up to the F above. The left and right arrows move the whole layout by an octave, up to three either way, and the up and down arrows transpose by a semitone at a time.
Can I use a MIDI keyboard?
Yes. Use the MIDI button in the control bar to connect it. Web MIDI is supported in Chrome and Edge on desktop and on Android; Safari on iPhone and iPad has no Web MIDI, so the on-screen keys are the only input there.
Are the pedals real?
The three of them behave as they should. Hold Alt (or N) for the sustain pedal, V for the soft pedal and B for the sostenuto. A hardware pedal sending CC 64 is treated as sustain.
Is the sound synthesized?
No. The hall plays a sampled grand piano, so a held note decays the way a recorded instrument does rather than holding a flat electronic tone. That is also why the first notes need a moment after you arrive: the samples are still loading.
