SpecEnvoy Music

One place for every piece you can play with a following score, across piano, cello, violin, viola, flute and clarinet. Filter by instrument, era or ensemble; see how each ensemble is built (who plays what); tap straight into the player.

Ever wondered how a written score becomes music you can hear, live in your browser? A plain-language walk through the real technology — real recorded instruments, a sampler, a scheduler and audio effects. Pick your level: for everyone, for musicians, or for engineers.

A growing collection of lush, film-scale pieces for cello and piano — all our own original music (and, in time, public-domain arrangements), tagged by mood, setting and feel. Find one for the moment and play it with a following score. Original or public-domain only — never a cover of a copyrighted song.

A large, growing library of string-quartet movements — Haydn, Mozart, Beethoven and dozens more. Pick any one and it plays with all four instruments (two violins, viola and cello) while the cello line follows on screen. Every piece is public-domain music, sourced note-for-note from OpenScore (CC0) with its credit and licence.

Every public-domain piece from "play with score", auto-arranged into an electronic track and played live in your browser — synth bass, pads and a four-on-the-floor beat, all built from scratch. Tap and listen.

Who actually built these instruments? Two museums, switchable: the great string schools (Amati, Stradivari, Vuillaume) and the piano makers from Cristofori's invention to Steinway, Heintzman of Toronto and Yamaha. Tap a maker for a placard and zoom into real instruments — Met CC0 and public-domain photos only.

Hold a sustained drone on any pitch and play your scales against it to train your intonation — the fastest way to a better ear — and keep time with a full-featured metronome. Tuner on the way. Works on any phone; nothing to install. Built for strings first, useful for any instrument.

A fast flashcard drill for reading notes across the three clefs a cellist uses. Real engraved notation, instant feedback and streaks; pick which clefs to practise. Works on any phone, nothing to install.

Never learned to read a score? Start here. A from-scratch interactive primer on the staff, clefs, sharps and flats, keys, rhythm, the tie-vs-slur trap, triplets, chords and dynamics — every idea has a live example you can play, right in the browser. Plus a written glossary.

Advanced harmony and analysis, learned by doing it. Name intervals, chords, cadences and non-chord tones; identify seventh chords, analyse with Roman numerals and spot secondary dominants — all with engraved notation you can hear. Organised by the RCM Level 9 & 10 syllabus, with an interactive circle of fifths alongside.

A private test page running a duplicate of the playback engine, so audio-buffer experiments can't touch the live pages. Tap a mode, play the 2-cello piece, report whether there's sound and whether it clacks — on your phone. If a mode wins, we merge it back into the real engine.
