Music has always had a prominent place in Sami Hammis life. After gaining extensive stage experience with the Tölzer Knabenchor (Bad Tölz Boys' Choir) he attended the Musikgymnasium der Regensburger Domspatzen (Music High School run by the renowned Regensburg Cathedral Boys' Choir) where he received intensive musical tutoring, attending singing classes and learning to play the piano, violin and oboe.

The first composition assignments started coming in straight after his graduation from high school: Sami Hammi was asked to compose the music for film projects. Subsequently, he attended the Rotterdam Conservatory where he studied composition and piano and on his return to Munich he completed an internship with Digital Editors Music. His work as ghostwriter for various projects soon attracted assignments in his own right composing music for commercials, television films and series, as well as other DVD productions and short films.

Sami Hammi has been working as a freelance composer since 2003; further facets of his work include orchestration, arranging and music preparation for various projects.
