Music on the Hill welcomes the autumnal season with Music in Nature, a concert of the Chamber Chorus — 12 professional singers — with artistic directors David H. Connell and Ellen Dickinson. The concert is Sunday, Oct. 14, at 3 p.m., at Wilton Presbyterian Church, 48 New Canaan Road. Donations will be welcomed, $20 is suggested.

Connell will conduct a program of works by notable contemporary composers: Finzi, Górecki, Hearne Hovhaness, Paulus, and Whitacre. Selections range from a setting of ancient Chinese poetry to a song of the anti-apartheid movement. Nature recurs as a grounding and restorative theme.

The Chamber Chorus, known for its a capella performances, is Music on the Hill's professional choral ensemble. It is featured in a spring and fall concert each year.
