Question 1

What is a virtual piano?

Accepted Answer

A virtual piano is a browser-based piano keyboard you play with your computer keys, mouse or touch. It uses the Web Audio API to synthesize the actual sound in your browser — no plugin, no download, no audio file streamed in. You can practice chords, scales and simple melodies without installing any software.

Question 2

Which computer keys play the piano?

Accepted Answer

The first row of letters (A through ;) maps to the white keys of C major across two octaves. The second row (W through M) maps to the black keys. The keys are labelled on each piano key for reference. Use Z and X to shift the keyboard down or up by an octave.

Question 3

How does the record and replay work?

Accepted Answer

Hit the record button, play a melody, then stop. Your timing and key presses are stored locally in the browser — nothing is uploaded. Press play to hear the playback at the same speed you recorded. Use it to capture a phrase you want to remember or share the timing with a student.

Question 4

Do I need a MIDI controller?

Accepted Answer

No. This virtual piano works entirely with computer keys, mouse clicks or touch — no hardware required. If you do have a MIDI controller, the Web MIDI API is broadly supported but not wired into this minimal tool; for serious practice, install a dedicated piano VST.
