The Sound of Music is a musical (musical theater) 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. Many songs from the musical have become standards (Standard (music)), including the title song "The Sound of Music (The Sound of Music (song))", "Edelweiss (Edelweiss (song))", "My Favorite Things (My Favorite Things (song))", "Climb Evry Mountain" and "Do-Re-Mi".

The original Broadway (Broadway theatre) production, starring Mary Martin and Theodore Bikel, 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 film musical (The Sound of Music (film)) starring Julie Andrews and Christopher Plummer. The Sound of Music was the final musical written by Rodgers and Hammerstein; Hammerstein died of cancer nine months after the Broadway premiere.
