Christin Bonin wrote her dissertation, titled “The Broadway Belt – Implications of Gender, Ethnicity and Social Order” as a consequence of her nearly life-long passion for the belt voice. She graduated as Master of Arts in Musicology at LMU, has been teaching at LMU and in various workshops and masterclasses, and participates at international conferences.

Before taking the path of academic research and teaching, Christin Bonin was a member of the Staatstheater Karlsruhe and Bayerische Staatsoper in Munich and appeared in over forty operas. She was also several years on tour through Europe playing in operettas and musicals and singing popular music, for example with internationally known stars like Udo Jürgens.


Based on her very first studies and degree as a voice teacher, she created in 2004 her own vocal school “Star me up” in Munich to follow her passion for teaching contemporary repertoire, especially musical theatre, jazz, and pop. Christin Bonin used her experience of 11 years teaching belting and directing her vocal school to develop a method of belting technique.

As a consequence, she became the author of the vocal method books “Belt Voice Training – Singing with a Belting Voice” and “Singing Makes You Happy,” before putting her research, experience, and passion for belting on an academic level.
