A concert grand you can play in the browser, with all six Brandenburg Concertos rendered from the orchestral score and played back on the keys.
Brandenburg Piano is a concert grand in a browser tab with Bach's six Brandenburg Concertos arranged onto it — all nineteen movements, every orchestral part folded into two hands. You can sit and listen while the keys light up, play along on your computer keyboard, or take the piano on its own and ignore the concertos entirely.
It is not a game and we do not pretend otherwise. It is here because it is one of the few things in this collection where the interesting part is audio rather than a renderer, and because it does the unglamorous work properly: real sampled piano, real scores, and credits for both.
How to play Brandenburg Piano
- Click Play first — browsers will not start audio until you do, and the sample pack loads on that first press.
- Choose a concerto, then a movement. Playback controls cover restart, previous and next movement, a position scrubber and a speed control.
- To play along, use the keyboard rows the guide shows: Z S X D C V G B H N J M for the lower octave, Q 2 W 3 E R 5 T 6 Y 7 U for the upper one. There are octave-shift and sustain controls beside them.
- The piano roll above the keys shows what is coming; "follow the illuminated keys" is the mode to use if you want to learn a passage rather than listen to one.
- There is a reduced-motion setting if the falling-note visualisation is distracting.

Why it's worth your time
The sound is a sampled instrument — the Salamander Grand Piano V3 by Alexander Holm, used under CC BY 3.0 — rather than a synthesised tone, which is why it holds up over a whole movement. The scores come from public MIDI and MusicXML editions, credited in the app under CC BY-NC 4.0. Both credits are in the interface, not buried in a repository.
Reducing an orchestra to one keyboard is an editorial act, not a conversion, and the app says so: there is a note on interpretation in the credits panel. Our copy is about 17 MB, most of it piano samples. The keys respond to touch, so a phone or tablet plays it — only the play-along key mapping needs a real keyboard.
How it was made and where it lives
Hosted on Vercel. The author publishes as DeryaTR_. Original: https://brandenburg-piano.vercel.app/. The Play button above runs our own unmodified copy, so the game keeps working here if that page goes down — which on free hosting usually has nothing to do with the author. Nothing about the game itself is changed, and the original stays linked from every page.
