"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 Alpine hills. The song is sung by Captain Georg Ritter von Trapp as he rediscovers music and a love for his children. Later on in the show it is sung as a defiant statement of Austrian patriotism by the Von Trapp family in the face of the pressure put upon CaptainVon Trapp to join the navy of Nazi Germany.
