 "Social evenings" for members and guests were held first in Cambridge and then in such renowned Boston locations as the Revere House, the Tremont House, and the original Parker House.Then, the association would gather ten to twelve times a year to hear some of the leading chamber musicians of the day and to share a post-concert supper.Whether the white-tie-and-oyster affair of the 19th century or the baked bean, Welsh rarebit, and ale collation of the present, the social evening remains the heart of the organization.
