Is IMSLP legal to use?

Yes, for works in the public domain in your country. IMSLP is a legitimate archive run by a non-profit foundation and has been operating since 2006. Each file is tagged with its copyright status. Files marked "Public Domain" are free to download and use without restriction. Files with Creative Commons licenses have conditions attached - read the license before using them commercially or making derivative works.

Can I use public domain scores for performances?

Generally yes - public domain scores can be performed, reproduced, and distributed freely. However, a modern edition of a public domain work may itself be under copyright (due to the editor's contribution). Check the specific edition you are using. If you want to be safe, look for scores explicitly marked as public domain rather than using a recent critical edition.

What if the score I need is not on IMSLP?

For works still under copyright, you will need to obtain a licensed copy - through rental libraries, publisher catalogues, or directly from the composer. For obscure public domain works not yet uploaded, you can sometimes find digitized scores through national library portals (Library of Congress, Bibliothèque nationale de France, etc.) or by searching specific manuscript repositories. University music libraries are also worth contacting.

How do I know if a score is in the public domain?

The rule varies by country, but the most common threshold is 70 years after the composer's death. A composer who died in 1953 would have works entering the public domain in most countries in 2024. IMSLP tags each file with its copyright status per country. The US has additional rules for works published before 1928, which are all public domain regardless of the composer's death date.

Where to Find Free Orchestral Scores Online (and How to Use Them)

Centuries of orchestral music belongs to everyone - from Haydn to Mahler, from early Baroque to the early twentieth century. Here is where to find it, what you will get, and what to do once you have the PDF.

The public domain is enormous

Most of the core orchestral repertoire - the symphonies, overtures, concertos, and tone poems that fill concert programmes around the world - is in the public domain. That means the scores are legally free to download, print, perform, and distribute. No licensing fees, no rental agreements, no publisher permissions required.

The catch is that "free" does not always mean "easy to find" or "ready to use." Scores are scattered across multiple archives, in varying quality, and often as full conductor scores rather than the individual parts your players actually need. This guide covers the main sources and what you will find at each one.

What is the public domain?

Copyright has a limited term. In most countries, works enter the public domain 70 years after the death of the creator. A composer who died in 1950 has works entering the public domain in most of Europe and the UK in 2021; in the US, pre-1928 publications are public domain regardless of the composer's death date.

For orchestral music, this means composers up to roughly the early twentieth century are fully in the public domain - Beethoven, Brahms, Dvořák, Mahler, Debussy, early Stravinsky, early Bartók. Later twentieth-century composers - Shostakovich, Britten, Messiaen - are generally still under copyright and require licensed copies.

One important nuance: a modern edition of a public domain work may itself carry a new copyright, based on the editor's scholarly contribution. An Urtext edition of a Beethoven symphony published in 2010 may be copyrighted even though the underlying music is not. If you need a legally clear copy, look for editions explicitly marked as public domain, not just any recent publication.

The main sources

IMSLP - the Petrucci Music Library

IMSLP is the largest and most comprehensive public domain music library on the internet. As of 2025, it hosts over 700,000 files covering more than 180,000 works. For orchestral music, it is almost always the first place to look.

Searching IMSLP is straightforward: look up the composer, find the work, then scroll through the files. Each file entry shows the edition, the uploader, the page count, and critically the copyright status - usually "Public Domain" or a Creative Commons license with conditions.

File quality varies widely. Some uploads are high-quality scans of original printed editions with good contrast and clean margins. Others are lower-resolution scans with warped pages or handwritten annotations. Typeset editions in PDF from notation software are generally the cleanest. When multiple editions are available, compare the thumbnails and page counts before downloading - a larger file is often (though not always) a better scan.

IMSLP also includes performing parts for some works, which can save you the extraction step entirely. Check the "Parts" section under each work before downloading the full score.

MuseScore.com

MuseScore.com is a community platform where users share scores created in MuseScore notation software. The catalogue is vast and covers a much broader range than IMSLP - arrangements, transcriptions, modern works, and popular music alongside classical repertoire.

Quality on MuseScore is inconsistent. Community-created scores range from careful, accurate transcriptions to rough approximations. For professional use, treat anything from MuseScore as a starting reference rather than a performance source. The platform is most useful when you need an arrangement or a transcription that does not exist in the published repertoire.

MuseScore files can be downloaded in PDF, MusicXML, and MIDI formats, which makes them useful if you need an editable source rather than just a PDF.

Choral Public Domain Library (CPDL)

CPDL is focused specifically on choral and vocal music. If you are working with choral-orchestral repertoire - oratorios, cantatas, masses, requiems - CPDL is worth checking alongside IMSLP. It tends to have good coverage of Renaissance and Baroque choral works, and many scores include both the full conductor score and separate vocal parts.

National library digitization projects

Many national and university libraries have digitized their collections and made them publicly available. These are most useful for historical manuscripts and early printed editions:

Library of Congress (loc.gov) - extensive digitized music collection, particularly strong for American repertoire and early twentieth-century holdings.
Bibliothèque nationale de France (gallica.bnf.fr) - strong French and European holdings, including manuscript sources.
Bayerische Staatsbibliothek (digitale-sammlungen.de) - major German-language collection, good for classical and early Romantic period sources.
Internet Archive (archive.org) - a broad aggregator; search quality varies, but it captures material that does not appear elsewhere.

These sources are most valuable for historical research or for finding specific manuscript sources. For general performance use, IMSLP is usually faster and better organized.

What format will you get?

The vast majority of public domain scores you find online will be PDFs. On IMSLP, almost everything is PDF - either scans of printed editions or typeset files exported from notation software.

MuseScore additionally offers MusicXML and MIDI downloads, which are useful if you want to edit the score in notation software. MusicXML is the most portable format between notation programs - Sibelius, Finale, Dorico, and MuseScore all import it with reasonable results, though layout and formatting rarely survive perfectly.

For part extraction, PDF is what you want. Image-based processing - which is how Unscore Me works - operates on the rendered page, not on the underlying notation data. This means it works regardless of which software generated the PDF, and it handles scanned scores just as well as typeset ones.

Checking file quality before you download

Look at the thumbnail on IMSLP. Most pages show a preview image. Check that the staves are straight, the contrast is good, and the margins are not cut off. If it looks poor in the thumbnail, the full file will not be better.
Check the file size. A very small file for a long work often means a low-resolution scan. A full orchestral score of 100 pages should typically be at least a few MB.
Prefer typeset over scanned where available. Typeset PDFs (from Sibelius, Finale, Lilypond, etc.) render at any resolution and have perfect contrast. Scanned PDFs are fixed at scan resolution and vary in quality. Both work for extraction, but typeset scores give cleaner results.
For scanned scores, 300 DPI is the minimum. Below that, staff line detection becomes unreliable. IMSLP scans are usually adequate; very old or volunteer-digitized collections can be lower quality.
Watch for annotations. Some scores on IMSLP are library copies with handwritten markings, stamp impressions, or stickers. These do not affect part extraction, but they will appear in the output PDFs.

Once you have the PDF: extracting parts

A full score PDF gives you everything - conductor score, all instruments across all pages. But your players need individual parts. The traditional approach (printing and photocopying section by section) takes hours and produces inconsistent results.

Unscore Me handles this automatically. Upload the full score PDF; the detection pipeline identifies each instrument row across every page; you label the parts in the editor; and you download one clean PDF per instrument. The whole process takes minutes.

This works with any PDF source - IMSLP downloads, MuseScore exports, scans from your own library. The only requirement is that the score has clearly printed staves at a reasonable resolution. If it is readable to the eye, it is processable.
