Sonata No. 6 (An Unexpected Endurance)

Sonata No. 6 (An Unexpected Endurance) sits in our piano hub as a full-length instrumental-friendly piece (~4 min). Peter Bille Larsen released it under CC0 / public domain; Soundex only catalogs it — we do not re-license or watermark the audio.

Source: Internet Archive item 6-peterbillelarsen-sonatas. Soundex hosts the catalog page; the audio remains the public-domain / CC0 original.

• License: CC0 / public domain — commercial use, no attribution required
• Genre hub: Piano
• Moods: relax, focus
• Creator workflows: podcast, youtube, corporate

Longer than a sting, shorter than a film cue: at ~4 minutes you can cover a scene without an obvious loop point. Mark the waveform in your editor; do not assume the Archive file has perfect silence at 0:00.

Where this track belongs in a timeline

1. Use the opening for titles, the middle for process footage, and the last 20 seconds for an end card if the energy drops.
2. Do not time-stretch more than ~5% or the bed will warble on vocals.
3. Link the genre hub Piano in your description if you mention Soundex.
4. If you need SFX instead, leave this page and open sound effects — do not treat this MP3 as foley.

Clients ask “is this copyright free?” Show them the badge on this page, not a screenshot of a random Google result.

This page is part of Soundex topical authority for free piano music — not a duplicate of other track pages. Next: more Piano, the full catalog, or guides on YouTube music and royalty-free vs copyright-free.

CC0 music is the most permissive option: creators waive rights so you can use tracks anywhere forever — no credit, no royalties, no claims when you download from Soundex.

What does the CC0 license allow?

Under Creative Commons Zero you may copy, modify, remix, sell and redistribute — commercially or personally — without asking permission or naming the artist.

• YouTube and TikTok monetization
• Client work you hand off
• Apps, games and templates
• Paid ads where credits are impossible
• Remixes and derivative sound design

How to choose CC0 vs other Soundex licenses

1. Need zero paperwork and zero credits? Choose CC0.
2. Okay crediting the artist? CC-BY unlocks more tracks.
3. Need commercial use without CC branding? See no-attribution.
4. Still confused? Read Creative Commons guide.
5. Compare terms in royalty free vs copyright free.

Tip: CC0 is ideal when your deliverable will be re-edited by clients who will never see your description box.

People also ask about CC0 music

Is CC0 the same as public domain?

Functionally very close — the waivers put the work as close to public domain as law allows.

Can I sell a pack that includes CC0 tracks?

You can include them in larger products, but do not claim you own exclusive rights to the raw track.

Do I still need to download from Soundex?

Yes — use our files and track pages so you know exactly what you received.

Every Soundex track shows its license on the download page. Compare options on our licenses hub, or read royalty free vs copyright free and the Creative Commons guide before you publish.
