In the artist's words:

CONSTANT is a young, mixed vocal ensemble that has been directed by Judith Mohr since 2015. The currently 40 singers have many years of choral and vocal experience. The chamber choir is dedicated to choral literature from all eras at a high musical level. The broad repertoire ranges from a cappella pieces from the Renaissance to works of choral symphonic music and modern compositions.

CONSTANT has performed numerous well-attended concerts in recent years and has thus also gained national recognition. The stylistic diversity and musically detailed development of the programs are at the forefront of the joint music-making and are repeatedly praised by listeners. Highlights of their joint musical work include their participation in the WDR choir competition "Singen macht glücklich", in which the choir was nominated as one of 10 out of 317 applicants. In 2017, the choir won the NRW state choir competition in its category and was also honored at the subsequent German Choir Competition 2018 in Freiburg. In 2019 and 2023, the chamber choir accepted an invitation to perform in Stuttgart's Stiftskirche as part of the renowned "Stunde der Kirchenmusik" concert series. In 2022, CONSTANT was involved for the second time in the Reformation celebration at the Trinitatis Church. The singers are regular guests at Cologne's Antonite Church, among others, with whose congregation the choir maintains close ties. In 2022, the first three cantatas of Bach's Christmas Oratorio were performed together with the Cologne Baroque Orchestra in the Trinitatiskirche in Cologne and - together with the Overbach Chamber Choir - in Aldenhoven. In 2023, CONSTANT sang the opening concert at the VDKC Festival in Lübeck and accompanied the festive service for the 850th anniversary of the cathedral Bach's St. Matthew Passion in 2025 marked the first collaboration between the CONSTANT chamber choir and the Südwestdeutscher Kammerchor Tübingen, both of which are conducted by Judith Mohr. The Cölner Barockorchester was once again engaged as the orchestra.
