fuguing became more integrated and eventually evolved to be the longer part of the song. There is good evidence that by 1760, English tune books including fuguing tunes were circulating in the American colonies; the first English fuguing tune printed in America appeared in the hymnbook Urania, or A Choice Collection of Psalm-Tunes, Anthems, and Hymns by James Lyon. Soon, fuguing tunes were being written in great profusion by American—especially New England—composers. Karl Kroeger (see reference below) has documented the publication of almost 1300 fuguing tunes during the period 1750–1820. Among the principal composers of New England fuguing tunes ("Yankee tunesmiths") Irving Lowens lists the following: William Billings, Daniel Read, Jacob French, Timothy Swan, Stephen Jenks, Supply Belcher, Abraham Maxim, Lewis Edson, Joseph Stone, Elisha West, Justin Morgan, and Daniel Belknap. Fuguing tunes and fugues The similarity of the terms "fugue" and "fuguing tune" means that the two forms are easily confused. A fuguing tune certainly is not some kind of failed attempt to write a fugue, as an ill-informed musicologist once asserted. This is plain from the different structures of the two genres: in a fugue, the voices take turns coming in at the very beginning of the piece, whereas in a fuguing tune that moment comes about a third of the way through. Moreover, in a fugue the musical material used at each entrance (the so-called "subject") is repeated many times throughout the piece, whereas in a fuguing tune it normally appears just in the one location of sequenced entries, and the rest of the work is somewhat more homophonic in texture. Indeed, "fuguing" does not derive from "fugue". Rather, as Irving Lowens points out, both terms hark back to a still earlier, more general usage (ultimately from Latin fugere "to flee"). He cites the words of Thomas Morley, who wrote (in 1597 in his Plaine and Easie Introduction to Practicall Musicke), "We call that a Fuge, when one part beginneth and the other singeth the same, for some number of Notes (which the first did sing)." In modern musical terminology, this is called a "canon", though Lowens interprets the passage more loosely, explaining that "fuging is pretty well synonymous with what we today call the technique of imitative writing".
