The “Chamber Choir Constant at the Antoniter City Church” is a young, mixed vocal ensemble from Cologne, currently consisting of approximately 28 male and female singers. Founded in 2006 by Harald Jers as an addition to the CONSONO Chamber Choir, it is affiliated with the “Antoniter City Church” in Cologne. An important aim of the choir is to present high standard musical performances of essentially unknown choral literature with music ranging from the renaissance, baroque, classical and romantic periods, through to modern, experimental compositions for choir. The specialised knowledge and research of choir director Harald Jers in the areas of vocal training, musicology and choir acoustics are directly incorporated into all rehearsals and concerts, and also applied to aspects concerning stylistics, singing and choral formation. With this know-how, the chamber choir has improvised with a saxophonist at the “Aachen Churches Open Night”, presented thematically-oriented a capella concerts, appeared at an important special concert at the Protestant Kirchentag (church gathering), and also recorded film music for the ARD and ZDF. A particular highlight has been the historically accurate performances of the St. John Passion by J. S. Bach, with accompanying lighting effects to support the music.
