"In the decade preceding the [Revolutionary] war, Bayley was by far the most active American compiler and publisher, accounting for some two-thirds of the 21 sacred music collections that survive from the years 1764-74. His tunebooks introduced to New England a large repertory of mid-century British sacred music, including several works that came to be standard favorites." Grove Dictionary of American Music Vol. I, p. 163.
