When your son’s voice changes, please contact us as soon as possible to discuss the best way forward. As the NCCGB Junior Choir sings treble repertoire only, you should contact your son’s singing teacher or head of music to ask whether they feel that he still has sufficient treble range to be part of the NCCGB Junior Choir; if there is any doubt, we will be happy to arrange for him to be heard. If he has sufficient range in his new voice and it has settled, your son will be invited to move into the Senior Boys’ Choir for his next course.
