During this time he wrote his first successful compositions, including the premiere of his chamber opera Die Wette, and made initial contact with the publisher Breitkopf & Härtel.
[4] From 1953 to 1966 Strohbach was a music teacher at the gymnasium St. Ursula in Hanover, but continued to work as a freelancer at the theater Landesbühne, which covers performances all over Lower Saxony, from 1951 to 1993.
[2] His works were published by Breitkopf and Härtel, Wiesbaden, Edition Ferrimontana, Frankfurt, Möseler Verlag, Wolfenbüttel, and Strube-Verlag, Munich.
[14] In 2006 the choir recorded his Gospel motet Jesus heilt einen Gelähmten on a CD to celebrate 60 years.
While, in this instance, Strohbach deliberately adheres to traditional forms of composition, the narrative sections of his work are dealt with freely: He renders them through recitation as well as through a finely coloured, grand a cappella motet.
[17] Strohbach composed a program for the annual Advent concerts of the Knabenchor Hannover in 2011 in the Marktkirche, Freuen sollen sich die Himmel (The heavens shall rejoice).
