<P> Although this song has parallels with "You'll Never Walk Alone," the song shares musical similarities with the song "Something Wonderful" from The King and I. Both songs are played at a similar broad tempo, and both songs have accompaniments punctuated by heavy chords in the orchestral score . </P> <P> The song has often been sung by operatically trained voices in professional stage productions . In the original Broadway production it was sung by Patricia Neway, in the original London production it was sung by Constance Shacklock, and in the original Australian production it was sung by Rosina Raisbeck . </P> <P> In the original stage play, the Mother Abbess sings the song at the end of the first act . When Ernest Lehman wrote the screenplay for the film adaptation, he shifted the scene so that this song would be the first major song of the second act . When Robert Wise and his film crew were filming this scene, Peggy Wood had some reservations about the words, which she felt were too "pretentious ." So they filmed Peggy Wood in silhouette, against the wall of the set for the Mother Abbess' office . Peggy Wood's singing voice is dubbed by Margery MacKay, the wife of the rehearsal pianist Harper MacKay, as Wood was not able to sing the high notes of the song . Rodgers wrote the piece in the key of A, with a modulation towards the end of the piece, making the last note that the Mother Abbess sings in the film an A flat (Ab5). With the popularity of the stage play it would seem Peggy Wood was not alone . MacKay set the bar high with "Climb Ev'ry Mountain ." Given the range of the piece and the average age of the actor playing Mother Abbess, the oldest character in the story, the song has proven daunting for many actresses over the years . </P> <Table> <Tr> <Td> </Td> <Td> This section needs additional citations for verification .
