Virtual Accordion
Piano-accordion layout: hold melody keys for reed sustain; press the left bass buttons for soft accompaniment.
Melody range A2–E5
Melody notes are recorded automatically. Playback lights keys, follows your mapping, and can export MP3. Bass buttons are live accompaniment only.
Virtual Accordion You Can Practice With, Not Just Click Through
A lot of browser accordion toys play a couple of samples and stop there. This Virtual Accordion is built for people who actually want to work an idea: hold melody keys for reed sustain, sketch left-hand bass and chords on a Stradella-style board, then keep the take. Record as you play, listen back with your original timing, share a link with a friend, or download an MP3 when something is worth keeping. No install, no account wall — open the page and start.
Record the melody, then keep or send it
As soon as you play the piano-style right hand, the sequence recorder starts building a take with pitch and timing. Hit play to hear what you actually phrased — rests and all — not a flat grid of notes. When a phrase works, copy a share link so someone else can open the same page and hear it, or export an MP3 for your phone, lesson folder, or a rough demo. Left-hand buttons stay live accompaniment while you play; the recorded line is the melody you carried on the keys.
- Melody keyboard from roughly A2 to E5, using real accordion reed samples with light pitch-shifting between recorded roots.
- Left board laid out in circle-of-fifths columns: bass, major, minor, and dominant-7 buttons under soft, filtered piano tones so accompaniment sits under the reed without fighting it.
- Hold a key to sustain; release for a short fade — closer to bellows reed behavior than a one-shot click toy.
- Computer keyboard mapping you can customize and save, plus optional MIDI for the melody side.
- Built-in metronome, note labels (scientific, solfège, or numbered), and an optional audio visualizer when you want feedback while practicing.
- Mobile Performance Mode for phones and tablets: compact layout, landscape-friendly playing, and the same record / share / MP3 loop as desktop.
Mobile Performance Mode: An Accordion Simulator Built for Thumbs
On a phone, a full accordion body usually means tiny keys and constant scrolling. Performance Mode opens a compact, landscape-friendly layout so the bass board and melody keyboard stay usable. You still get recording, playback with timing, share links, and MP3 download — the same workflow as on a laptop, trimmed for touch. If you practice on the bus or want to demo a tune without unpacking a real box, this is the mode that makes the page feel like an instrument instead of a shrunk screenshot.
- Compact accordion body in one view: bass buttons and melody keys without hunting through the desktop chrome.
- Landscape-first playing with fuller use of the screen; rotate when your browser cannot lock orientation for you.
- Recorder stays on while you tap — capture a melody idea, replay it, then share or export without switching apps.
- Metronome and volume controls remain available so a short phone session can still be deliberate practice.
- Exit anytime and return to the full page layout for mapping, MIDI setup, or longer desktop work.
What Performance Mode Changes on Phone and Tablet
1) Put the whole instrument in reach
Desktop layout spreads controls for mouse users. On mobile, that same layout fights you. Performance Mode packs the playable surface — left bass grid and right melody keyboard — into a compact body you can see and tap without endless zooming. The goal is simple: play a phrase with both hands before the idea fades.
2) Keep the practice tools that actually matter
A smaller screen does not mean a stripped-down toy. You can still watch the sequence build as you play, pause and resume recording, turn the metronome on for a steady pulse, and replay with key highlights so you see which melody notes fired. That feedback loop is what turns casual tapping into useful practice.
3) Share or download before you forget the take
Finished a chorus on your phone? Copy the share link and send it to a bandmate or student. Prefer a file? Download MP3 in the browser and drop it into a voice-memo folder or lesson archive. You do not need a DAW install just to prove a melody sits well on accordion color.
4) Switch back to desktop controls when you need them
Performance Mode is for playing. When you want to remap computer keys, connect MIDI, or tweak labels and visualizer settings, exit to the full page. Use each layout for what it is good at instead of forcing one UI to do everything on every device.
How to Use This Online Accordion for Practice and Sharing
1) Play melody, then add bass when you need a floor
Start on the piano-style keyboard at the bottom — mouse, touch, or the default computer-key rows. Hold a key to keep the reed sounding; release to stop with a short fade. Turn on note labels if you are learning the layout or teaching someone else. When the tune needs grounding, tap a round button on the left board: bass for a low root, M / m / 7 for a soft major, minor, or dominant chord. Keep left-hand volume modest so the reed line stays clear.
2) Let recording capture the take while you play
You do not have to arm a separate track first. Melody notes build the sequence as you go, with timing included. Pause when you need a breath, resume when you are ready. On playback, rests and phrasing stay where you put them, and the active keys light up so you can check fingerings or show a student what you meant. Optional MIDI works for the melody side if you prefer a controller; notes auto-release after a short hold on this page.
3) Share a link or download MP3 when it sounds right
Happy with a run? Copy the share link — the other person opens this accordion page and hears your performance with the original rhythm. Need a file for a playlist, social post, or homework drop? Export MP3 in the browser. On a phone, open Performance Mode first so the layout is playable, then use the same share and download steps. That loop — play, hear, send, or save — is what separates a useful practice page from a one-minute demo.
An Accordion Website Built for Sketches, Lessons, and Travel Practice
This page is for folk and pop players checking whether a tune sits in a comfortable accordion range, teachers who need a quick left-hand button demo, songwriters who want reed color without unpacking a VST, and anyone traveling without their instrument. It will not replace a full concert accordion — and it does not pretend to. It does give you a clear melody keyboard, a usable bass sketch pad, and a way to keep what you played.
I sketched a chorus on the melody keys, exported MP3, and sent it to my duo partner before rehearsal. They knew the phrasing I meant without me typing tab that could be read three ways.

"The bass buttons are simplified, but they are enough to outline I–IV–V while the right hand carries the tune. Students get the idea of the left board without staring at a blank wall of unexplained circles."

"Reed sustain on hold is what sold me. One-shot accordion toys never felt right. Recording with timing means I can judge whether a phrase works before I forget it."

"Performance Mode on my phone is how I check range between gigs. Share link when I want feedback; MP3 when I want the take in my voice-memo pile."
