HANOVER, N.H. — Wanted: pianos to be played at bus stops, parks, general stores and other places in parts of New Hampshire and Vermont.

To celebrate its 50th anniversary season, the Hopkins Center at Dartmouth College is sponsoring a piano “street project.”

The center is looking for old upright pianos. The idea is to create works of art for the public.

Agreements are in place with multiple towns, businesses and property owners to place pianos around the Upper Valley in July, including Ledyard Bridge connecting Hanover to Norwich, Vt.; the Tip Top Building in White River Junction, Vt.; the Dartmouth Green; and the Montshire Museum of Science in Norwich.
