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 vetted.

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.
