Chipmunk soul is a style of hip hop music that features sped-up vocal samples, originating in the 2000s. Early users of the style included Just Blaze, RZA, and Kanye West.[1][2]
The name "chipmunk" is a reference to Alvin and the Chipmunks, a 1960s musical act featuring sped-up vocal recordings.[3]
Although the style originated by sampling soul music recordings, the term "chipmunk soul" now includes the use of samples from other musical genres including reggae, rock and world music.[3]
