Problem
A public-domain composition is paired with a copyrighted modern arrangement, but the creator clears only the underlying work.
Solution
Root Cause / Diagnostic:
Copyright law splits musical works into the underlying composition and derivative arrangements. While an original composition by Bach or Beethoven is in the public domain, a modern arranger's unique harmonic adaptations, tempo restructuring, or orchestration create a new, independently copyrighted derivative work.
Actionable Fix:
1. Audit the sheet music and audio recording provenance to verify whether the performance utilizes the original Urtext historical score or a copyrighted contemporary arrangement.
2. Replace the contested audio track using the YouTube Studio Editor audio replacement tool or mute feature if the derivative arrangement was used without a sync license.
3. Source replacement classical recordings exclusively from verified authentic historical Urtext catalogs (such as Musopen or IMSLP public domain marked editions).
Pro Tip:
Check the arranger's copyright status on IMSLP/Petrucci Music Library; to be safely public domain worldwide, both the original composer AND the specific arranger/editor must have passed away over 70 years ago.
