Virtual Piano
Free online virtual piano. Play 25 keys from C4 with mouse, multi-touch or keyboard, with sustain pedal, octave shift and rich sound. 100% local, offline.
How many keys does this virtual piano have?
It offers 25 keys — two octaves plus one note from C4 up to C6. With the octave shift buttons you can move the whole keyboard up or down across six octaves.
Can I play it with my computer keyboard?
Yes. The keys A through K map to the white keys starting at C, while W, E, T, Y and U play the black keys in between, and Space activates the sustain pedal.
Does it support multi-touch on phones and tablets?
Yes. The piano uses pointer events, so you can press several keys at once on touchscreens, slide your finger across the keyboard, and it works alongside computer keyboard input.
How is the piano sound produced?
Each note is synthesized in real time in your browser with additive synthesis: a fundamental plus several harmonics with a natural decay envelope, creating a warm electric-piano-like tone without any audio samples.
What does the sustain pedal do?
When sustain is on (Space or the checkbox), released notes keep ringing and fade out slowly instead of stopping immediately — exactly like holding down the right pedal on a real piano.
Is my playing recorded or sent anywhere?
No. All sound is generated locally in your browser via WebAudio and nothing leaves your device. No recordings are made and no data is uploaded.
Why is there a short delay when I press a key?
There should be almost none — synthesis starts instantly. If you notice latency, the audio device may have a large buffer; closing other tabs and apps that use sound usually helps.
Can I play chords?
Yes. Press several piano keys with multiple fingers or mouse buttons, or hold several computer keys at once — every key sounds independently, just like a real instrument.
How to Use Virtual Piano
This virtual piano synthesizes every note locally in your browser with additive synthesis — a warm electric-piano tone with no samples to download. Play it with the mouse, multi-touch or your computer keyboard; nothing is recorded or uploaded.
- Click or tap the keys to play. On touchscreens you can press several keys at once and slide your finger across the keyboard.
- Use the computer keyboard too: A–K play the white keys from C, W E T Y U play the black keys.
- Hold Space or check "Sustain" to let notes ring out like a real piano pedal; uncheck it for a dry, clipped sound.
- Move the octave up or down with the − / + buttons to reach lower or higher registers (the label shows the new bottom note).
- Adjust the Volume slider to taste, and toggle "Key labels" to show or hide note names and keyboard hints on the keys.
Try a simple melody: right hand on the on-screen keys, left hand holding two keys as a chord — the independent per-key synthesis makes chords sound clean.
