Introducing SpecEnvoy Music
Published 2 July 2026
A new corner of Learn for anyone who loves music, or is learning an instrument: meet the great composers on a timeline, hear the masterworks played from the score, and practise with tools that live right in your browser.
When we started Learn, we said we'd go beyond maths. SpecEnvoy Music is where we've gone — and it turned into the richest thing we've built. It's five free tools, all bilingual, all working on any phone, everything sourced from the public domain.
The great composers, on a timeline you can scroll
Start with The Cello Through Time and its sibling The Violin Through Time. Scroll the centuries like a river — Vivaldi and Bach through Haydn, Boccherini, Paganini, Dvořák and Elgar — and tap any name for a museum-style placard: who they were, why they mattered, and the works that count. Portraits and biographies come from Wikipedia; every note you hear is public domain.
And you can actually hear the music
This is the part we're proudest of. Tap a work and it plays from the score — real engraved notation scrolling in time with the sound, note by note. Every playable piece is complete, not a teaser excerpt: full Bach suite movements, Saint-Saëns' The Swan, arrangements of Brahms, Schumann and Fauré, and more. There's even an ensemble mode, so a quartet plays with all its voices and you can solo any one of them. Because two instruments share the same great repertoire, an arrangement built for one timeline enriches the other.
Who actually built the instruments?
The Cello Makers is a little museum of the great workshops — Amati to Vuillaume, Cremona to Paris. Tap a maker for a placard, then zoom deep into real instruments photographed by the Met. As always, only public-domain and open-access images.
Two tools for people who play
- Practice Studio — a drone to train your intonation, a full metronome, and a tuner. A practice companion in a browser tab, built for strings first but useful for any instrument.
- Sight-Reading Trainer — a fast flashcard drill for reading notes across bass, tenor and treble clef, with real notation, instant feedback and streaks.
Why public domain, always
SpecEnvoy is a commercial site, so we hold ourselves to a strict rule: every score, portrait and photograph here is free for anyone to use, checked piece by piece, with credit shown in the player. It's slower to build that way. It's also the only way we're comfortable putting the world's musical heritage in front of your kids for free.
Whether you're a lifelong listener or a beginner with a bow in hand, come and scroll through a few hundred years of music.
