The organization raised $26,610.65, placing it 10th overall among the 390 participating nonprofits representing the arts, education, animal welfare, human services, housing and more.

The annual 24-hour online donation event, put on by Fairfield County’s Community Foundation, raised $1.6 million from 12,666 donors. Since its inception in 2014, a total of $9.3 million has been raised from 97,065 total gifts for more than 1,500 nonprofits, according to the foundation.

Based at the WEPCO complex on New Canaan Road, Music on the Hill provides opportunities for choral musicians and singers, handbell ringers and instrumentalists to participate in performances, workshops and festivals, and social events with fellow music-lovers.
