Virtual Piano

The home row plays the white keys — A S D F G H J K L and the ; key walk up from C — and the row above supplies the black keys: W E for C#/D#, T Y U for F#/G#/A#, O P continuing into the next octave. The mappings are printed on each key (toggleable), so you learn them by playing. Z shifts the whole keyboard down an octave, X up, from C2 to C6. Chords work: press multiple letters simultaneously, exactly like real keys.

Because the sound is synthesized in real time — oscillators and filters shaped to behave like a struck string — rather than playing back gigabytes of recorded piano samples. The trade is deliberate: sampled pianos sound richer but need large downloads and licensing; synthesis loads in milliseconds and works offline once the page is open. For what this is for — finding melodies, learning the layout, checking intervals — the synthesis is honest and pleasant. For performance-grade tone, a sampled VST is the right tool.

It mimics a piano's damper pedal: with sustain off, releasing a key stops the note quickly, the way dampers fall back onto strings; with sustain on, released notes ring out over a couple of seconds and overlap into each other. It's the difference between detached playing and the washy, connected sound of pedaled piano. Notes also decay naturally even while held — a struck string always fades — which is a detail cheap virtual pianos skip and your ear notices.

For melodies, chord progressions, and understanding the keyboard's geography — absolutely, and two octaves covers most melody lines and the letter-key layout is how a whole generation of virtual-piano players learned. Its honest limits: no velocity sensitivity (every note strikes at the same volume, so no dynamics practice), and computer keyboards can miss some 3+ key combinations by hardware design. Treat it as the sketchpad; if playing sticks, weighted keys are where technique actually develops.
