Conductor Linda Blanchard and pianist Sean Fleming, a married musical duo, have been collaborating in choral music ventures in midcoast Maine for 25 years. They lead Sheepscot Valley Chorus, St. Cecilia Chamber Choir, and St. Andrew’s Episcopal Church choirs, all of which are currently accepting new members. Non-auditioned Sheepscot Valley Chorus is based in Wiscasset; rehearsals are Tuesdays, 7 to 9 p.m., at the Congregational Church. St. Cecilia Chamber Choir is an auditioned chorus rehearsing Wednesdays from 7 to 9 p.m. at St. Andrew’s Church in Newcastle. Sopranos and altos should be able to sing with a straight tone and all singers should have a finely tuned ear and be eager for a challenge. To schedule an audition, email Blanchard at audition@ceciliachoir.org or call 380-2768. Junior and youth choirs at St. Andrew’s Church in Newcastle rehearse Wednesday afternoons; the senior choir rehearses Thursdays at 7 p.m. The choirs provide music for the 10 a.m. Sunday services (the children join monthly).
