Gong Logic

A small, growing library of public-domain piano pieces you can play along with in the browser. Every score here is engraved dynamically — our own renderer draws the notation live from each piece’s note data (and the downloadable PDFs are generated the same way), so the layout is a work in progress and may differ from the original engraving. Each piece links back to the public-domain source it was transcribed from: the original engraving (via the Mutopia Project) and the work’s page on IMSLP.
