Interpolation
Recreating a portion of an existing song rather than using the original recording.
Definition
An interpolation is when artists recreate a portion of an existing composition (melody, lyrics, or musical phrase) in a new recording rather than sampling the original master recording. Interpolations require licensing from the composition's publisher but not from the original recording's owner.
This distinction can make interpolations cheaper than samples, as only one license is needed. However, significant interpolations require negotiation similar to sampling.
Why It Matters
Interpolation offers a legal way to reference existing songs while potentially avoiding master recording clearance costs. Understanding the distinction helps plan creative decisions with budget implications.
Proper interpolation clearance prevents costly legal issues after release.
Examples in Practice
Recreating a classic melody line with new instrumentation rather than sampling the original recording.
An interpolation clearance costing $50,000 versus potential $150,000+ for the original sample.
Legal disputes when artists argue similarity was coincidence rather than intentional interpolation.
