Beatrice Harmon

Demian Herzog

Demian Herzog received early training on the violin from Jens Lohmann at the Zürich Music Conservatory and became acquainted with the viola there. Several 1st prizes in the Swiss Youth Music Competition with his string quartet quickly followed. Around the same time he started playing the piano and soon discovered his love for jazz music. A semester of Environmental Sciences at the Swiss Federal Institute of Technology (ETH Zürich) convinced him that Pedagogy and School Music at the Zürich University of the Arts are the more congenial career path with viola studies under Wendy Enderle-Champney. Orchestral experience as principal violist in the Swiss Youth Symphony Orchestra as well as in Stringendo Zürich followed. Today, Demian Herzog divides his time between chamber music (Modulor Quartet), instrumental pedagogy and school music.
