The Holy Trinity Cathedral choir performs four essential roles within the church community. They lead and invigorate the congregation’s singing, rendering songs that the congregation may not be able to sing themselves. Additionally, they function as a smaller faith-based group within the church, facilitating spiritual growth. Lastly, they offer their voices and talents to sing intricate and beautiful music, both to honor God and uplift the congregation. The Holy Trinity Choir, with utmost reverence, fulfills these functions. Comprising approximately twenty members, the choir showcases both instrumental and vocal prowess. Members diligently rehearse songs and actively participate in all church masses and events, including those within the diocese. Furthermore, they eagerly partake in competitions held on various occasions in and around Coimbatore.
