The string intro of Pharrell Williams' song "Marilyn Monroe" was written by which violinist?

The string intro of Pharrell Williams’s song “Marilyn Monroe” was written by violinist Ann Marie Calhoun.

The song opens Pharrell Williams’s 2014 album Girl with a prominent orchestral string passage before the main vocal section begins. That distinctive introduction is credited to American violinist and string arranger Ann Marie Calhoun, making her the specific answer to the question.

“Marilyn Monroe” was written and produced primarily by Pharrell and released as the album’s second single in March 2014. Its credits also connect the track with Hans Zimmer, whose orchestral work and film-score background helped shape the song’s expansive opening sound. Kelly Osbourne contributes spoken vocals.

The question can cause confusion because Pharrell is the principal artist and songwriter, but the credit asks specifically about the string introduction. It also does not ask who played every violin part on the recording; it asks who wrote the opening string arrangement.
