The Spalding Gentlemen's Society is one of the oldest extant learned societies in the world. At the time of its foundation over 300 years ago such societies were popular and membership was viewed as an important attribute of middle-class life. Most societies were short-lived and extant references to them are rare. What sets Spalding over all others is not only its longevity but also the quality of its records, which contain numerous references to music. This article aims to present the musical activities of the Society and to put them into the context of the early eighteenth-century English and European musical world. It begins with a discussion of the annual anniversary concerts and a detailed study of the 1738–46 programmes, commenting on the music performed and those who took part; these programmes are given as appendices. This research is further augmented by an examination of the music-related matters discussed at their meetings and other events that took place in Spalding. It may be impossible to ascertain how unique the Society's musical activities were, but it is rare to have such detail, and this is the first time that these important records, at least in relation to music, have been discussed in any depth.
