Starting from childhood I played trumpet and clarinet in a brass band and later on also in a school band. Additionally I played violin and trumpet in a youth orchestra and subsequently in a student orchestra. As an adult I joined several amateur symphony orchestras including some university orchestras. Sometimes I played beat and soul music as well as jazz in a band of up to ten musicians. I started singing in the schools boys choir and was a member of several amateur choirs, especially of the Hamburger Singakademie.I studied mathematics, computer science, philosophy and musicology ending up with the highest degree and was full-time teaching and researching at several universities for 45 years.
