First an elementary school teacher, he worked for decades as the church musician at St. Lukas in Schweinfurt, where he held annual festivals, conducted a notable choir, was responsible in the Bavarian organization of chorale conductors, and was a lecturer at the music university of Würzburg.
Born in Kunzendorf, Gunsenheimer left Silesia with his family at the end of World War II.
[1][2] His career as a musician began when he founded and conducted a regional teachers' choir named "Fränkischer Singkreis" (Franconian singing circle).
His studies included "Elementare Musik- und Bewegungserziehung" (Elementary music and movement pedagogy), which brought him in personal contact with Carl Orff.
For these concerts, he was able to attract musicians who would not normally play at a small church, such as the Bamberger Streichquartett (Bamberg String Quartet), the violinist Wolfgang Forchert, soloists at the beginning of their career such as soprano Barbara Schlick, contralto Waltraud Meier, tenor Christoph Prégardien, and the guitarist Michael Tröster.
