De Minimis

Under the EU AI Act, an AI model trained on broad data that can be adapted to a wide range of tasks. Subject to specific transparency and compliance obligations.

Interpolation

Replaying or re-recording a melody, lyric, or musical phrase from an existing work rather than sampling the original recording. May avoid master clearance but still requires composition clearance.

Master Recording

The original, finalized recording of a song. Ownership of the master is separate from ownership of the underlying composition.

Mechanical License

A license that grants the right to reproduce and distribute a musical composition. Required for covers, remixes, and other reproductions of a copyrighted song.

Neighboring Rights

Rights related to copyright that protect performers, producers of sound recordings, and broadcasting organizations. Vary significantly by jurisdiction.

Non-Exclusive License

The right of an individual to control the commercial use of their name, image, likeness, or persona. A subset of personality rights.

Royalty-Free

A licensing model where the user pays once (or nothing) and does not owe ongoing royalties. Does not mean copyright-free. Terms vary by provider.

Sampling

Using a portion of an existing sound recording in a new work. Typically requires clearance of both the master recording and the underlying composition.

Sound Recording
