Online Piano
A full playable keyboard — mouse, touch or your computer keys — with four synthesized instrument voices, a real sustain pedal, octave shifting across a seven-octave range, and a record button that lets you hear your own melody played back instantly.

A Keyboard You Already Know How to Use
Most typing-piano tools ask you to memorize an unfamiliar chart before you can play a single note. This one puts the answer directly on the keys themselves — the letter printed on each piano key is exactly the key to press for that note, updating live as you shift octaves, so there's genuinely nothing to look up or remember beforehand.
The layout itself is deliberately close to touch-typing home position: A through J covers the white keys of the lower octave, with W, E, T, Y and U filling the black keys directly above the gaps where they belong, mirroring how black keys actually sit relative to the white ones on a real keyboard. The upper octave continues immediately below on Z, X, C, V, B, N and M, with Q, R, I, O and P covering its black keys — so both full octaves shown on screen are playable from the keyboard at once, not just the first one. Comma and period, right next to that second row, shift the whole thing up or down an octave without ever reaching away from where your fingers already are.
Four Instruments, One Set of Keys
Rather than loading sampled recordings of a real piano — which means downloading audio files before a single note can play — every voice here is built from oscillators and envelopes generated live by the Web Audio API. Piano layers a triangle-wave fundamental with a bright, fast-decaying harmonic to mimic a hammer strike; Electric Piano uses frequency modulation, the same core technique that gave classic Rhodes-style electric pianos their glassy character; Organ stacks four pure sine harmonics that hold steady for as long as a key is down, because a real organ doesn't decay while a key is held the way a piano does; and Synth Pad runs two slightly detuned sawtooth waves through a soft low-pass filter for a wide, slow-swelling texture built for holding chords rather than quick runs.
Switching between them mid-session costs nothing — there's no loading delay, since the next note you play simply uses a different set of oscillator settings rather than a different audio file being fetched. In practice, Piano and Electric Piano end up covering most melodic playing, Organ is the one worth reaching for when a held note's exact timing needs to be obvious rather than smoothed over, and Synth Pad tends to get used less for melodies and more for holding a chord underneath one, letting it ring out while a melody is picked out on top with a second hand.
Recording a Melody, Then Hearing It Back
Clicking Record doesn't just start a timer — it logs the exact pitch, start time and release time of every note you play, from any combination of mouse, touch and keyboard input, for up to 60 seconds. Clicking Play afterward replays that captured sequence through the same synth engine, reproducing chords and overlapping notes with their original timing intact, not just a flattened list of single notes. It's a small addition, but it turns the tool from something you play once and forget into something you can actually use to check whether a melody you just improvised was any good.
Download WAV takes that same captured sequence one step further: rather than replaying it live, it renders the whole recording offline — the entire timeline of notes, chords and releases calculated in one pass rather than played back in real time — and hands back a genuine 16-bit WAV file using whichever instrument was selected. That means a melody worth keeping doesn't have to live only inside this browser tab; it can be dropped straight into a DAW, attached to a message, or just saved for later.
Who Actually Plinks Around on a Browser Piano
Beginning piano students use it to find and check notes without needing an instrument nearby — a keyboard at a desk, a laptop between lessons, or a phone on a commute all work identically. Songwriters and producers reach for it to quickly test a chord voicing or melodic idea before committing it to a DAW. Teachers use it to demonstrate a scale or interval on a shared screen without hauling in a keyboard, and a music therapist or hobbyist working with someone who's never touched a piano can hand over a laptop with genuinely nothing to install or configure first. And plenty of people use it for exactly what it looks like — a few idle minutes figuring out a tune by ear, which genuinely doesn't need anything more sophisticated than a keyboard that responds reliably and sounds decent.
Two Different Sessions at the Keys
A student working through a scale exercise sets the Organ voice specifically because its steady, undecaying tone makes it obvious the moment a held note is released too early — a piano's natural decay tends to hide small timing mistakes that an organ's flat sustain exposes immediately. Once the fingering feels solid, switching to Piano for the same exercise gives a more musical, realistic feel to practice against. Keeping steady time throughout is easier alongside the Online Metronome, running in a second tab at whatever tempo the exercise calls for.
A songwriter chasing a chord progression that's stuck in their head switches to Synth Pad, holds down three or four notes at once to hear how the voicing actually sits, and hits Record the moment something clicks so the exact progression isn't lost to memory a few minutes later. If the idea needs a tempo attached before moving into a DAW, the BPM Tap Tempo Calculator finds that number in a few taps.
Where a Screen Stops Being a Piano
Nothing about a flat glass or plastic surface reproduces the weighted resistance of a real piano key, or the subtlety of touch-sensitive dynamics where how hard you press actually changes the volume and tone — every note here sounds at a fixed velocity regardless of how a mouse click or tap was made. For building real finger technique, strength and dynamic control, there's genuinely no substitute for practicing on a weighted keyboard or acoustic piano.
What a browser piano is legitimately good for is everything around that physical practice — checking a note, testing a chord, sketching an idea, or just playing for a few minutes when no instrument is within reach. Treated as that kind of quick, always-available reference rather than a replacement for a real instrument, it holds up well against what it's actually asked to do.
