Play our free online virtual piano keyboard. Features selectable instrument tones, quick chord lookup, and MIDI/MP3 recording.
Click keys or use your computer keyboard. Covers middle octave (C4–C5).
WebAudio triangle-wave synthesis. If you hear nothing, click any key first to unlock browser audio.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This virtual piano lets you play a three-octave range from C3 through C6. Press an on-screen key with a mouse or touch screen, or use the labeled computer-key shortcuts for the middle octave. The note names and shortcut labels can be shown or hidden, and a volume control adjusts playback level.
The sound is synthesized in the browser rather than recorded from an acoustic piano. Each note is created at its corresponding pitch and given a short envelope, so this is useful for trying a pitch or sketching a short musical idea. It is not a piano lesson, sheet-music reader, recording studio, or MIDI export tool.
In play mode, pressing a virtual key or mapped computer key sounds that note. The mapped row runs from A for C4 up through K for C5; the sharps use W, E, T, Y, and U between the corresponding white-note shortcuts. Several notes can be held together to audition a basic interval or voicing.
Chord lookup accepts supported chord names such as Cmaj7, Dm, or G7, identifies the parsed root and quality, and highlights the notes in the keyboard. The lookup recognizes a defined set of spellings and chord qualities; an unrecognized or extended symbol may not resolve. It does not analyze chords played by listening to the user.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Click or tap a key and hold it to sound the note. On a computer, use the shortcut labels shown on the middle octave. The page may need the first click or tap before browser audio can begin.
Move the volume slider to adjust level. Turn note labels on or off to keep the keyboard readable while you play.
Switch to chord lookup and enter a supported name, for example Cmaj7. Review the root, quality, note list, and highlighted keys; choose the play control to hear the chord.
For practice, play one note at a time and watch its label, then try a simple chord such as C major. Use a physical instrument when you need weighted keys, pedal response, or acoustic dynamics.
Use cases
See how the tool fits into real work and everyday tasks.
A beginner can show labels, press a key such as C4, and connect the note name with its position on a keyboard.
A learner can enter a supported chord symbol and inspect which notes the lookup maps to highlighted keys before practicing the voicing.
Use touch or a computer keyboard to audition a short melodic fragment, keeping in mind that the range is limited to C3–C6 and the sound is synthesized.
Q&A
Find concise answers to common questions and confusing cases.
The middle octave maps A, S, D, F, G, H, J, and K to C4 through C5, with W, E, T, Y, and U mapped to the intervening sharps. Use the labels displayed on the keyboard as the guide.
Browsers commonly require a user gesture before audio playback. Click or tap a piano key once, then check the device volume and the page’s volume slider.
No. This keyboard plays notes and provides chord lookup; it does not record performances or export MIDI or MP3 files.
The lookup supports specific root-note spellings and a defined list of chord qualities. Try a conventional spelling such as C, Am, or G7; the tool does not infer a chord from audio input.
