Musical theatre is a form of theatrical performance that combines songs, spoken dialogue, acting and dance. The story and emotional content of a musical – humor, pathos, love, anger – are communicated through words, music, movement and technical aspects of the entertainment as an integrated whole. Although musical theatre overlaps with other theatrical forms like opera and dance, it may be distinguished by the equal importance given to the music as compared with the dialogue, movement and other elements. Since the early 20th century, musical theatre stage works have generally been called, simply, musicals.

Although music has been a part of dramatic presentations since ancient times, modern Western musical theatre emerged during the 19th century, with many structural elements established by the light opera works of Jacques Offenbach in France, Gilbert and Sullivan in Britain and the works of Harrigan and Hart in America. These were followed by Edwardian musical comedies, which emerged in Britain, and the musical theatre works of American creators like George M. Cohan at the turn of the 20th century. The Princess Theatre musicals (1915–1918) were artistic steps forward beyond the revues and other frothy entertainments of the early 20th century and led to such groundbreaking works as Show Boat (1927), Of Thee I Sing (1931) and Oklahoma! (1943). Some of the best-known musicals through the decades that followed includeMy Fair Lady (1956), The Fantasticks (1960), Hair (1967), A Chorus Line (1975), Les Misérables (1985), The Phantom of the Opera (1986), Rent (1996), Wicked (2003) and Hamilton (2015).

Richard Charles Rodgers (June 28, 1902 – December 30, 1979) was an American composer who worked primarily in musical theater. With 43 Broadway musicals and over 900 songs to his credit, Rodgers was one of the best-known American composers of the 20th century, and his compositions had a significant influence on popular music.

Rodgers is known for his songwriting partnerships, first with lyricist Lorenz Hart and then with Oscar Hammerstein II. With Hart he wrote musicals throughout the 1920s and 1930s, including Pal Joey, A Connecticut Yankee, On Your Toes and Babes in Arms. With Hammerstein he wrote musicals through the 1940s and 1950s, such as Oklahoma!, Flower Drum Song, Carousel, South Pacific, The King and I, and The Sound of Music. His collaborations with Hammerstein, in particular, are celebrated for bringing the Broadway musical to a new maturity by telling stories that were focused on characters and drama rather than the earlier light-hearted entertainment of the genre.
