The Main Choir The Main Choir currently consists of approximately 14 singers who sing every Sunday and meet almost every Friday (7.30pm) from September to July to rehearse at Holy Trinity. The Augmented Choir The Augmented Choir is an extra group of singers who double the size of the Main Choir and, as a result, more challenging music is sung. As a rule, the Augmented Choir aims to sing at Carol Services before Christmas, on the two Sundays before Easter Sunday and once in the ‘summer’ term. The Augmented Choir rehearses on Fridays (7.30pm) in October to December, late January to Easter and sometime after Easter until the final engagement. Augmented Choir members are welcome to sing at any other time with the Main Choir and some certainly sing on Remembrance Sunday, Christmas Eve, Christmas Day morning and on Easter Sunday. One or two members also sing in the Main Choir from time to time when the Augmented Choir doesn't have any other immediate commitments.
