What are scat performers?

Scat performers are entertainers who produce rhythmic vocal improvisations, also called scat singing. It involves using nonsense words, vocalizations, and syllables for improvisational purposes. Scat performers combine sounds, create melodies, and use their voices in a highly creative and expressive manner to create unique improvisational pieces. They often perform alongside jazz, blues, or a capella groups, adding an element of spontaneity and improvisation to the music. Notable scat performers include Louis Armstrong, Ella Fitzgerald, and Bobby McFerrin.
