for narrator, SATB soloists, and SATB choir unaccompanied, with optional bones In this compelling work for narrator, soloists, and choir, Sheehan presents an engaging musical dramatization of Charles Dickens's A Christmas Carol. Dickens's text has been artfully abridged by Matthew Guard to facilitate concert performance, and the narration is seamlessly woven into Sheehan's richly diverse score. Suited to performance in a variety of settings, this work sees imaginative arrangements of traditional carols and vibrant and accessible original music combine to bring a familiar festive tale to life.

for soloists and SATB unaccompanied Inspired by Rachmaninoff's All-Night Vigil, Vespers is a 12-movement English-language work in the Eastern Orthodox tradition. Suited to concert and liturgical settings, it draws from a variety of Orthodox chant traditions, with Sheehan's use of asymmetric metres enhancing the textual expression of the chosen prayers, psalms, and hymns. The work is infused with a deep religious sentiment, and the artful use of chiasmus places the ancient hymn 'Phos Hilaron' ('O gladsome Light') at its centre, defining its supreme message of light and hope. Virtuosic solos are underpinned by rich choral textures or offset by characterful interjections, with movements for chorus alone equal in impact. In a work that considers the past, present, and future of Orthodox liturgical music in America, Sheehan creates a distinctly American idiom rooted in the centuries-old Eastern Orthodox musical tradition, displaying a unique voice that is cohesively ancient and modern.

for SATB unaccompanied This is a declamatory setting of a popular Easter text by Gerard Manley Hopkins in an upbeat 7/8 metre. Featuring compelling interplay between choral sections, a slower reflective passage, and a rousing conclusion, this anthem will bring a fresh sound to Easter services and concerts.

for SATB and organ or piano This Easter carol is based on J. M. Neale's translation of the Latin Piae Cantiones and occupies a captivatingly exotic soundworld. Sheehan's setting is in strophic form, with a texture that builds from verse to verse and with varying harmonizations, culminating in a dramatic cadence.

for SATB unaccompanied Let all mortal flesh keep silence is a reflective, homophonic setting of text from the fourth-century Orthodox Liturgy of St James. Sheehan's setting, an original rather than the customary pairing with the hymn tune 'Picardy', is steeped in the Orthodox tradition, and has pure harmonies and a beautiful stillness.
