Frédéric Yonnet (born 30 April 1973) is a French musician, producer and recording artist who is best known for his use of the harmonica as a lead in jazz, R&B, funk, gospel and hip-hop influenced music. His ability to play chromatic scales on a diatonic harmonica gives him access to twice as many notes as the instrument is designed to deliver.
Described by Rolling Stone as Prince's "killer harmonica player", Yonnet gained popularity for his on-stage performance with music icon Prince and his harmonica duels with the legendary Stevie Wonder. Yonnet has performed and recorded with a wide range of artists, including David Foster, Bob James, Patti Austin, Erykah Badu, John Legend, India Arie, Angie Stone, Kindred The Family Soul, Justin Bieber, Randy Jackson, The Jonas Brothers and Grand Corps Malade.
