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".

"Edelweiss" is a show tune from the 1959 Rodgers and Hammerstein musical The Sound of Music. It is named after the edelweiss, a white flower found high in the Alps. The song was created for the 1959 Broadway production of The Sound of Music, as a song for the character Captain Georg von Trapp. In the musical, Captain von Trapp and his family sing this song during the concert near the end of Act II. It is a statement of Austrian patriotism in the face of the pressure put upon him to join the navy of Nazi Germany following the Anschluss. It is also Captain von Trapp's subliminal goodbye to his beloved homeland, using the flower as a symbol of his loyalty to Austria. In the 1965 film adaptation, the song is also sung by the Captain earlier in the film when he rediscovers music with his children.
