The chamber choir Ensemble Companio will perform Sunday, April 3, at 2 p.m., at St. Matthew’s Episcopal Church at 36 New Canaan Road. The concert is part of the Arts at St. Matthew’s series.

The choir’s mission, according to a press release, is to “build bridges between people through authentic, inspiring performances of the finest choral music.” It’s name is taken from a late Latin form of companion.

The choir, marking its fifth anniversary, is composed of volunteers who perform throughout the Northeast. Its 2016 concert program — Warnings, Wisdom and Wit — is comprised of works “through which composers and/or writers of text give caution, dispense moral advice, or make pithy observations about society and life,” Director Joseph Gregorio wrote in his blog.

Among the pieces are and ancient French song called L’homme armé (The armed man) warning the listener about one bearing arms, and a movement from a Mass by French Renaissance composer Guillaume Dufay. These will be accompanied by sacred works by 19th Century composers Anton Bruckner and Charles Villiers Stanford, as well as a contemporary piece by Pennsylvania-based composer Kala Pierson on a Shakespeare text about love.

Arrangements of folk music from Colombia, England, Ireland, and Mexico; shape-note music from The Sacred Harp; an arrangement of a poignant warning from French singer-songwriter Francis Cabrel about the effect technology can have on communication and memory; and other pieces will also be offered.

Patron tickets are $60 and entitle the bearer to preferred seating. Regular tickets are $30, $15 for students.
