A vocal duet is a musical performance featuring two singers who harmonize and complement each other’s voices. This type of collaboration can occur in various genres, including classical, pop, and jazz. Duets often showcase the unique vocal qualities of each singer while creating a rich, layered sound. In a vocal duet, singers may alternate lines, sing together in harmony, or engage in call-and-response patterns. Famous examples include Mozart's operatic duets and contemporary songs by artists like John Legend and Alicia Keys. Duets can enhance emotional expression and create a dynamic listening experience.
