One of the most notable, but least studied, aspects of the 18th-century revivals that led to the rise of modern evangelicalism was the disputed place of hymn-singing. In his very first report on the unusual religious stirrings in Northampton, Massachusetts from 1736, Jonathan Edwards noted that although his congregation had already learned the era's new style of singing—"three parts of music, and the women a part by themselves"—the revival had worked an extraordinary musical effect:

Our public praises were greatly enlivened, and God was served in our psalmody as in the beauties of holiness. There was scarce any part of divine worship wherein God's saints among us had grace so drawn forth and their hearts lifted up, as in singing the praises of God.

Yet soon the fervor of hymn-singing, as well as what the newly revived were singing, came under fire. Not only were critics upset with what Edwards (in a later work defending the revivals) described as "abounding in much singing in religious meetings." Critics were also complaining that the revived congregations were singing "hymns of human composure," that is, hymns newly written by contemporaries rather than hymns paraphrased directly from the Psalms, which was then the only kind of hymnody widely accepted in most English-speaking Protestant churches.
