A thousand pieces you can play along with
Published 18 July 2026
The SpecEnvoy music library just passed 1,000 playable pieces — every one a complete work that plays live from real engraved notation, free, in your browser. Here's what's new, and how to get the most out of it.
The library, by the numbers
When we launched the music section, it played about a hundred pieces. Today it plays over a thousand: 486 songs — Schubert's Ave Maria and Ständchen, Brahms, both Schumanns, Fauré — with the melody following on screen while the piano plays; 364 string-quartet movements from Haydn to Dvořák with all four voices sounding; the famous piano repertoire from Clair de Lune and Für Elise to the Moonlight Sonata, Rondo alla Turca, Chopin's nocturnes, Liszt's Liebestraum and La Campanella; and 19 classic hymns in their traditional four-part settings. Browse everything in one place at Play with score — search by title or composer, or start from the famous-first strip.
Pieces whose tempo breathes
Some movements refuse to sit at one speed — the Pathétique's brooding Grave keeps erupting into its Allegro, and Grieg's In the Hall of the Mountain King famously accelerates. The player now follows the score's own tempo changes, so these pieces finally sound the way they're written. That's what unlocked the Pathétique and Tempest first movements and Mozart's D-minor Fantasia this week.
New tools for practising
Open any piece and you'll find three quiet additions made for practising, not just listening: an A–B loop — tap two notes on the score and the passage between them repeats until your ear (or your fingers) have it; a count-in that clicks one bar in the piece's own meter before playback; and on grand-staff pieces, a piano keyboard under the score with the sounding keys lit. They're small, but together they turn the library from a jukebox into a practice room.
Make something of your own
The Maker — our in-browser beat studio — grew up this week too: per-step accents, two drum kits, any key and scale, triplet and 6/8 grids, four chainable patterns for building a full song, and live recording from your computer keyboard. When you like what you've made, share it as a link — the whole beat packs into the URL, no account, nothing uploaded. Here's one we made writing this post.
Free means checked
SpecEnvoy is a commercial site, which is exactly why the sourcing rules are strict: compositions in the public domain, editions that are public domain or CC0, checked piece by piece — Mutopia editions with per-piece licences, OpenScore's CC0 engravings, and community engravings from the PDMX dataset cross-checked against scholarly editions. Every player links its source, and the licensing notes are published beside the code. Slower to build; the only way we'd build it.
Whether you're learning your first piece or just want Clair de Lune on while you work — it's all there, and it's all free.
