As a primarily liturgical Choir, the principal focus of music-making is the Mass, in celebration of which the boys and men sing music from the great history of the Church, in the fine acoustics of St. Paul's Church Harvard Square. Plainsong, Polyphony, Romantic and Contemporary composition are all represented in the choir's repertoire.
The boys sing at daily services, with the result that they have a large repertoire of boys-voice music. The Choir is accompanied by expert organ playing, and the liturgy is adorned with stylistically appropriate organ improvisation.
St. Paul's Church Harvard Square is home to one of very few traditional choirs of boys and men in the USA. In the past, this performing arts arm of the Boston Archdiocesan Choir School was also known as The Boston Boy Choir. The Choir of St. Paul's Harvard Square is supported by the only Roman Catholic Boys Choir School in America, while the professional men are drawn from local music colleges including the Longy School of Music, NEC and Boston Conservatory.
Major choir events at Saint Paul's include the Christmas concerts in December, and the spring concert in May.
The Choir is fed by a training choir of 4th and 5th grade boys known as 'The Trebles,' they sing three times each week. When a boys voice changes, he enters the 'Schola Cantorum,' who are a group of young men in the midst of vocal transition. They sing several times each month and rehearse each week.
