Movie Score for Treppe Aufwärts

Composed and produced the movie score for Treppe Aufwärts, a German feature drama (2015) by Mia Maariel Meyer. The music direction was built around scene tension, family conflict and editorial rhythm, from thematic sketching to final mix delivery.

Established a coherent sonic identity across key character arcs and supported emotional continuity between dialogue-driven and high-pressure sequences. The score approach helped connect narrative pacing from festival presentation to theatrical release in Germany.
