Characterized by its strong rhythm and smooth melodies, swing music often features big bands with brass instruments, woodwinds, and a rhythm section. The music encourages dancing, particularly the Lindy Hop and Jitterbug, making it a favorite in dance halls and social gatherings. The term "swing" refers to the rhythmic feel of the music, which creates a sense of movement and excitement. Notable musicians associated with swing include Duke Ellington, Count Basie, and Benny Goodman. Their contributions helped shape the genre and influence future styles of music.
