Notation and playback
Scores are engraved in your browser with abcjs 6.7.1, an MIT-licensed open-source library. Playback uses the same locally hosted piano samples and synthesiser as the other TOEA instrument tools, and the moving cursor follows the notes as they sound. Documentation: https://docs.abcjs.net/

Frequently asked questions
Are the starter melodies free to use?
Three short original tunes were written for this tool. Frère Jacques and London Bridge are traditional public-domain melodies, freshly transcribed without modern arrangements or lyrics. See the source panel.
Does transpose change the ABC text?
No. The visualTranspose option changes the engraved score. Playback and MIDI use the corresponding pitch shift once. The ABC download preserves what you typed.
Which ABC features can I use?
abcjs handles notes, rests, repeats, ties, chords, multiple voices and tempo changes. The editor accepts one tune of up to 20000 characters; playback is limited to 4096 notes and ten minutes. The syntax panel covers common notation.
Does MIDI retain notation?
MIDI stores the mapped performance at the shared writer’s fixed 120 BPM timebase. It preserves sounding pitches and timing, including written tempo changes, rather than the original key, meter or printed layout.
