Orchestrator Christopher Jahnke shares how he creates the way a show musically feels by breaking it down into individual instrumental parts; learned from his mentor William Brohn, orchestrator of "Miss Saigon" and "Wicked"; studied '50s music to give the "Grease" revival an authentic sound; and works closely with composer David Bryan on "Memphis" as music producer and supervisor at daily rehearsals and in the recording studio for the cast recording.
