Free Online Virtual Piano
Play piano online using your computer keyboard, mouse, or touchscreen. Multiple sound timbres, hardware audio recording, sustain pedal emulation, and zero latency.
Record & Export Your Performance
Captures live instrument & vocals with zero latency sidechain ducking. Export performance as .wav or .webm.
Acoustic Physics & Web Audio Synthesis
An acoustic grand piano creates sound when felt hammers strike steel strings stretched over a cast-iron frame. The vibration transfers through a wooden soundboard, creating rich harmonic overtones. Our virtual piano replicates this acoustic phenomenon using hardware Web Audio API additive synthesis, generating lowpass filter decay curves and realistic pedal resonance.
Multiple Timbre Configurations & Recording
Switch between Grand Piano, Rhodes Electric, Harpsichord, Organ, and Lead Synth timbres on the fly. Capture your songwriting sessions directly into lossless audio files using our browser-based recording pipeline.
Beginner Piano Tutorial: Master the 5-Finger Pattern
If you are new to playing piano, start with the C Major scale 5-finger pattern and the C Major chord. Position your right hand so your thumb (Finger 1) rests on C4, index finger (Finger 2) on D4, middle finger (Finger 3) on E4, ring finger (Finger 4) on F4, and pinky (Finger 5) on G4.
Curved Finger Joints
Curve your fingers as if holding a small tennis ball. Strike keys with fingertip pads rather than flat fingers.
Smooth Weight Transfer
Press each key smoothly, transferring hand weight from finger to finger without locking your wrist joints.
Syncopated Sustaining
Press the sustain pedal right after playing a chord to hold harmonics, then lift and press again as chords change.
