Compared with the older songs, Wesley and other new composers wrote with a simple structure. Rural farmers and workers expanded on these structures, creating complex songs which some musical conservatives railed against to no avail. It was in this context that a wave of itinerant singing masters, including William Billings, arose, creating hymns that remain standard across the country. This field was called the First New England School. Following Billings' pioneering footsteps were Supply Belcher, Andrew Law, Daniel Read, Jacob Kimball, Jeremiah Ingalls, John Wyeth, James Lyon, Oliver Holden, Justin Morgan and Timothy Swan.
