ShowbizU: What is a Sitzprobe? - Kenny Seymour & Tim Kashani

In this interview, Kenny Seymour and Tim Kashani explain the theatrical rehearsal milestone known as a sitzprobe. They describe the typical rehearsal progression, starting with a simple piano or minimal rhythm accompaniment, moving through weeks of rehearsals, and then transitioning to the orchestrator’s work. Once the full orchestration is ready, the cast experiences their first rehearsal with the complete orchestra or band—the sitzprobe—where they hear the full musical texture for the first time and sing along. The speakers highlight how this shift from piano to full instrumentation can surprise actors, requiring them to refocus as horns, drums, and guitars enter. They also discuss the unique experience of having the band onstage, fostering eye contact, a sense of family, and a collaborative, group‑effort atmosphere between musicians and performers.
