Melanie Pappenheim

 is a vocalist who worked with Murray Gold on some of the signature cues of the Russell T Davies era. Her voice was the major instrument in the version of the "The Doctor's Theme" heard in series 1 and 2. It was also used to underscore the "Doomsday" cue heard at Rose Tyler's initial separation from the tenth Doctor in the episode of the same name. Her voice was also heavily used on "Martha's Theme", "Astrid's Theme", "Seeking the Doctor", "The Doctor Forever" and "YANA (Excerpt)".

Because of her work on Doctor Who scores, she has been an integral part of two Doctor Who concerts: Doctor Who: A Celebration and the 2008 Doctor Who at the Proms. Her work is a part of the series 1 and 2 and series 3 soundtracks.

Outside of Doctor Who, she is arguably most prominent on the soundtrack of the Martin Scorsese film, Gangs of New York, as well as that of Far North. Her frequent collaborator is Jocelyn Pook, of whose ensemble Pappenheim is a key vocalist.
