What is an interpolation?

Definition

An interpolation is a re-recording of a melodic or rhythmic element from an existing song -- capturing the spirit of the original without using the original recording.

Interpolation in music -- explained

Interpolation differs from sampling in a legally crucial way: a sample uses the actual recorded audio from the original; an interpolation re-records the element with new players and instrumentation. This means interpolations typically require clearance only from the composition's copyright owner (publisher/songwriter), not the sound recording owner (label) -- often significantly cheaper and faster. Interpolations can be exact replicas of the original melody or loosely inspired variations. They are common in hip-hop and pop when producers want to reference a classic without paying full sample clearance costs. When an interpolation captures a 'substantial similarity' to the original melody, it still requires licensing. Famous interpolations: Mark Ronson and Bruno Mars's Uptown Funk interpolates Oops Upside Your Head; Nelly's Hot in Herre interpolates Funkadelic's Aqua Boogie; Notorious B.I.G.'s Big Poppa interpolates Between the Sheets by the Isley Brothers.
