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 memoir of Maria von Trapp, The Story of the Trapp Family Singers. Songs from the musical that have become standards include "The Sound of Music", "Edelweiss", "My Favorite Things", "Climb Ev'ry Mountain", and "Do-Re-Mi".

The original Broadway production opened in November 1959, and the show has enjoyed numerous productions and revivals since then. It has also been made into an Academy Award-winning 1965 movie musical. The Sound of Music was the final musical written by Rodgers and Hammerstein; Hammerstein died of cancer nine months after the Broadway premiere.
