Bertold Hummel's a-cappella choral music was mainly written for being used in services. The missa 'Cantabo Domino' was composed in 1958 for the liturgical festival of a Catholic student community in Freiburg im Breisgau. The piece can be performed by an amateur choir without great effort. Of modern harmony, the mass is exemplarily short and concise, with the comprehensibility of the text being to the fore. Hummel deliberately adjusted the melodic phrasing to the Gregorian chants to form a stylistic unity. This 'utility music' in the best sense of the word is ideal for any choir!
