WATERBURY — A concert of the original choral compositions of composer Carolyn Brown Senier of Orange, Mass., will be presented at 4 pm on Sunday, April 17, in Saint John’s Episcopal Church on the Green in Waterbury, the composer’s home town.

Geoffrey Hudson of Cummington, Mass., will conduct the 40-member Lake Mattawa Singers and nine-member Lake Mattawa Chamber Ensemble in selections from Ms Brown Senier’s The Mattawa Song Cycle.

With her husband Richard Senier, Carolyn Brown Senier retired to Lake Mattawa after more than two decades in the retail clothing business. She was proprietor of the well-known shop Celtic Weavers in Boston’s Faneuil Hall Market Place and Hartford’s Civic Center.

From 1953 to 1969, she was a sister with the Congregation of Notre Dame, serving as music liturgist. After the Second Vatican Council, she was music liturgist for the Diocese of Bridgeport, charged with interpreting the council’s intentions for music in Catholic worship services.

At Lake Mattawa, Ms Brown Senier has been a prolific composer, bringing her thorough understanding of chant and harmony to large, new compositions and a compilation of earlier work first designed only for women’s voices but now presented for full chorus.

Her works, “You Know Me,” “De Profundis,” “Song of Abraham,” “In Praise of Names,” “Summer Days” and “When I Knew” premiered to sell-out crowds in a series of central Massachusetts concerts during 2004.

All of those songs will be heard on April 17. Her signature song, “O, Praise Ye the Lord,” will also be performed.

Carolyn Brown Senier began creating original music when she was 18. She suspended her composing and teaching career in the late 1970s when she and her husband became proprietors of Celtic Weavers. She was also a public school teacher in Boston before returning to her musical roots after retirement.

Tickets for “The Mattawa Song Cycle: a gala choral concert celebrating the extraordinary music of Carolyn Brown Senier” are $20 for adults and $15 for students and seniors. Donations from the concert’s proceeds will go to Saint John’s Outreach Ministry and the Congregation of Notre Dame.

Advance tickets may be purchased at The John Bale Book Store, 158 Grand Avenue in Waterbury, by calling 800-215-8805, or by visiting MattawaSongCycle.com. Tickets will also be available at the church on the afternoon of the concert.
