The Kölner Domchor (Cologne Cathedral Choir) is the boys' choir at the Cologne Cathedral, officially founded in 1863. The choir rehearses three times per week. They perform regularly in services at the cathedral, and in concerts there and on international tours, including to Rome and the United States. The choir has been successful at choral competitions.
Choral singing had been present at the cathedral for centuries, but the Kölner Domchor was officially re-established in 1863, first performing in public on 1 November in a service with the Missa super Dixit Maria by Hans Leo Hassler and the offertory hymn O quam gloriosum by Tomás Luis de Victoria. The boys rehearse three times per week at the Kardinal-Höffner-Haus for regular performances in services at the cathedral, and for concerts there and internationally. Their broad repertoire ranges from Renaissance and Baroque music to contemporary music. They have collaborated with ensembles of historically informed performance such as Concerto Köln and Neue Düsseldorfer Hofmusik. They have performed, at times with the girls' choir at the cathedral, with Cologne institutions such as Kölner Philharmonie, Cologne Opera, Westdeutscher Rundfunk, and choirs and orchestras of the region.
The choir has been successful at national and international competitions, including the, being awarded the first prize in the category boys' choirs in 2002.
