The term 'Swing; Rhythm' can be summarized by the 4-letter word 'LILT'. Swing and Rhythm are two musical styles that are often combined to create a unique sound. Swing is a style of jazz music that originated in the 1920s and 1930s, characterized by a strong rhythm and syncopated melodies. Rhythm is a type of music that emphasizes the beat and tempo of the music. When these two styles are combined, they create a LILT, which is a light, graceful, and melodic sound.
