The Copenhagen Royal Chapel Choir is one of Scandinavia's oldest choral foundations that is richly steeped in tradition. The high artistic standard which has characterized the choir for 90 years has been achieved by means of the unique vocal training the choristers receive at Sankt Annæ Gymnasium (St. Anne's Gymnasium), the Copenhagen Municipal Choir School, and from the choir's duties at Copenhagen Cathedral (The Church of Our Lady).
