Interpolation, the musical technique of re-recording elements of a previously recorded song into a new composition, is becoming increasingly popular in pop music. This involves re-performing a melody, rhythm, or lyrical fragment, and it differs from sampling, which uses an existing recording directly.
Examples of interpolation include Shaboozey's hit 'A Bar Song (Tipsy),' which references J-Kwon's 'Tipsy.' Interpolation has roots in classical music, with instances such as Mozart's variations on folk songs and Bach's adaptation of Vivaldi's concerto elements.
The rise in interpolation is partly due to legacy artists selling their song rights, with companies like Primary Wave actively encouraging the technique to monetize their music catalogs. Recognizable patterns in interpolations can trigger dopamine release in the brain, creating a sense of pleasure and recognition for listeners.
