The Story of the Trapp Family Singers is a 1949 memoir written by Maria Augusta von Trapp, whose life was later fictionalized in Rodgers and Hammerstein's Broadway musical The Sound of Music in 1959.

The Sound of Music is a musical with music by Richard Rodgers, lyrics by Oscar Hammerstein II, and a book by Howard Lindsay and Russel Crouse. It is based on the 1949 memoir of Maria von Trapp, The Story of the Trapp Family Singers. Set in Austria on the eve of the Anschluss in 1938, the musical tells the story of Maria, who takes a job as governess to a large family while she decides whether to become a nun. She falls in love with the children, and eventually their widowed father, Captain von Trapp. He is ordered to accept a commission in the German navy, but he opposes the Nazis. He and Maria decide on a plan to flee Austria with the children. Many songs from the musical have become standards, including "Do-Re-Mi", "My Favorite Things", "Edelweiss", "Climb Ev'ry Mountain", and the title song "The Sound of Music".
