Axel Heintzenberg

Axel Heintzenberg grew up in Babenhausen in southern Hesse and appeared on stage in various musical productions as a teenager. After graduating from high school, he studied music education with a major in singing at Justus Liebig University in Giessen and subsequently worked as a musical director, vocal coach, and choir director.

He was a member of the Darmstadt Concert Choir under the direction of Wolfgang Seeliger, the Petruskantorei in Giessen under the direction of Herfried Mencke, and a founding member of the “Kicks’n’Sticks Voices” (vocal group of the Hesse State Youth Jazz Orchestra) under the direction of Wolfgang Diefenbach. Here he completed numerous work phases and workshops with renowned lecturers (New York Voices, The Real Group, Jeff Cascaro, among others), went on concert tours with the LJJO in China and South Africa, and participated in several CD recordings.

As a sound engineer and music producer, he worked for film and television—including DEIN SONG (ZDF/KIKA) and Das Mädchen und der Flüchtling (ARD)—and founded his own recording studio in Darmstadt with three colleagues in 2017.

Axel Heintzenberg has been employed at the Mainz State Theater since November 2022. In the 2024/25 season, he can be seen as Charon in Orpheus. The Art of Losing.

Outside of the theater, he continues to work as a vocal coach and composes music for children’s musicals.
