Under the guidance of Dónal Doherty, Codetta is an internationally acclaimed chamber choir based in Derry, N. Ireland. It was formed in 2001 under the auspices of the City of Derry Civic Choirs, which were established in 1997 with the support of Derry City Council, WELB and the Arts Council.

From an initial group of two choirs, the scheme has now expanded to cater for over 200 choristers performing in a variety of ensembles: Primary Girls, Junior Girls, Boys, Youth and Codetta. Codetta’s members are all originally from Derry but now live, work and study in towns and cities throughout Ireland, the UK and Europe. The wide-ranging repertoire that the choir performs is prepared at intensive weekend rehearsals held monthly throughout the year.

Codetta has given many concerts both locally and nationally, including a recent performance of the Bach Mass in B Minor. In 2006 it participated in the Advent Festival in Prague and has successfully competed in a range of international choral festivals, most notably reaching the final of the Grand Prix in Maribor in 2008 and winning awards at the Sligo and Cork International Choral Festivals in 2008/2009. In 2010 Codetta visited Tuscany performing in Florence, Reggello and Siena and most recently competed in the 2011 Montreux Choral Festival in Switzerland.
Codetta makes regular appearances on both radio and television, most recently taking part in a BBC Radio Ulster broadcast with the Ulster Orchestra and Kim Vaughan (former Codetta member) as part of a celebration of Derry being awarded the UK City of Culture for 2013.The group has collaborated on a CD with renowned Derry saxophonist Gerard McChrystal and recently took part in an episode of the award-winning TG4 series Seacht.
