Final answer:
20th Century Fox must contact The Ohio State University Marching Band for the Master (Synchronization) License to use their recording of "Beethoven's 5th" in a movie.
Step-by-step explanation:
If 20th Century Fox wishes to use the recording of "Beethoven's 5th" by The Ohio State University Marching Band in their movie, they need to contact The Ohio State University Marching Band for the Master (Synchronization) License.
This is because Beethoven's works have been in the public domain for over a century, meaning the composer's permission is not required. However, the specific recording by the band is their property. A music licensing agency can be contacted as an intermediary to facilitate the process if needed.
