Two octaves. Click, tap, or use your keyboard.
The virtual piano lets you play music directly in your browser using your mouse, touchscreen, or computer keyboard. It covers two full octaves and synthesises sound using the Web Audio API — a modern browser feature that generates audio without any plugins or downloads.
The white keys on the lower octave are mapped to A S D F G H J. The black keys are mapped to W E T Y U. The upper octave white keys use K L ; and the upper black keys use O P. This mirrors the layout of a standard piano keyboard.
Choose from four sound types: Piano-like (triangle wave with lowpass filter, closest to a real piano), Soft (pure sine wave, gentle and smooth), Retro (square wave, classic 8-bit sound), and Bright (sawtooth wave, rich and buzzy). The tone decays naturally after you release a key.
Use the Octave selector to shift the keyboard range up or down. C4 (middle C) is the default starting note. Lower octaves produce deeper sounds; higher octaves produce brighter, higher-pitched notes.
