Built by a musician,
for musicians.

Attacca is a curated library of public-domain classical scores. Search the catalog by composer, opus number, nickname, instrument, genre, etc. Download instantly, ready to perform.

Most score libraries treat the catalog as a data problem. Attacca treats it as a curation problem. Search understands how musicians actually talk (“Rach 2,” “Beethoven 109,” “Proko 3”). Every edition is checked against a United States public-domain standard before it's listed.

Attacca for iPad takes the catalog from search to music stand in seconds. Search a piece, download it, you're ready to perform. Annotation, metronome, built-in scanner, page jump, and everything else you'd expect from a great score reader.
