The Q W E R T Y U I O P row plays the white keys and the number row 2 3 · 5 6 7 · 9 0 plays the black keys — you can play several at once. With «Mark» on, click keys to mark them and play them with the space bar; marks are saved in the web address so you can share them.
Virtual Piano is a fully playable piano with a real sampled acoustic piano plus six synthesized sounds — classic and electric piano, organ, synth, strings and music box. Every key lights up and moves when you play it. Play by clicking the keys, with your computer keyboard, or by plugging in a real piano or keyboard over MIDI.
A fun way to practice is to pick a song from the library and play along in Waterfall mode, or record yourself and listen back — you can even download your take as audio or MIDI.
The keys map to your computer keyboard just like their physical position on the piano:
Hold several keys at once to play chords. Shift the range with the Octave − / + buttons, and turn on «Shortcuts» key labels in Settings to see the mapping on the piano itself.
Yes — connect a MIDI keyboard and use Chrome or Edge. It is detected automatically and its name appears in the badge at the top right. Anything you play on it sounds here and can be recorded too, with velocity sensitivity.
Yes — the piano adapts to your screen, showing fewer, bigger keys on small devices, and supports multi-touch so you can play chords with several fingers. You can also force a specific key density in Settings.
WAV is a finished audio file — share it or listen anywhere. MIDI stores the notes themselves, so you can open it in any music software (GarageBand, Ableton, MuseScore…) to edit the notes or change the instrument.
Marks are saved in the page address as you make them — just copy the URL from your browser and send it. Whoever opens it sees the same keys marked and can play them with the space bar.
