What’s the difference between smooth jazz and jazz? The main feature that sets these two genres apart is their instrumentalists' use of improvisation. Regular jazz instrumentalists incorporate improvisation more than smooth jazz instrumentalists do. Smooth jazz artists value the “smooth” over the “jazz” element of their music. Now, sit down and relax to the downtempo, smooth jazz of Kenny G, Sade, Anita Baker and George Benson. We hope you enjoy TuneIn’s Smooth Jazz Online Radio.
