Frequently Asked Questions

What makes Attacca different?

Cleaner files, better metadata, smarter search. Most score libraries store PDFs under cryptic upload IDs, so you end up with a messy library of unreadable filenames.

Attacca files have human-readable names. The catalog is organized by composer, opus number, and piece, the way musicians actually think.

And other apps only read scores. You still have to hunt down each one yourself, import it, and rename it before you can play a note. Attacca removes that whole step: the catalog and the reader are one app, so a score goes from search straight to your music stand. No hunting, no importing, no renaming.

What's in the catalog?

Most of the classical music canon: symphonies, concertos, chamber music, solo works, opera, lieder. Across the canonical composers and less-performed names.

How does search work?

Type how you actually talk. “Rach 2,” “Beethoven 109,” “Proko 3,” etc.

Typos, abbreviations, and foreign-language spellings all just work here.

What about different editions?

Multiple editions per work where available. The cleanest scan is surfaced first. Filter by editor, publisher, or year on the work detail page.

How does the iPad app fit in?

Attacca for iPad is the most integrated way to use our catalog. Search a score, download it, perform without friction. Annotation, metronome, scanner, page jump, and every feature you'd expect from a great score reader.

How does pricing work?

Free tier includes 10 downloads per month with an account. Both paid tiers include unlimited downloads plus library sync across iPhone, iPad, and web:

• $3.99/month, billed monthly.
• $19.99/year, billed annually.

No per-download fees on either tier.

Is everything legal?

Every piece in the catalog is verified as public domain in the United States. Each file passes a multi-gate review process before it's added, and we only store works with a clear US-PD determination.

Public domain status varies by country. If you're outside the US, you're responsible for ensuring use of any score complies with your local copyright law. We don't make claims about public domain status outside the United States.

Can I request a piece that's missing?

Yes! Please send a message below. We're constantly researching and adding new editions based on what musicians ask for.
