Final answer:
The English Reformation introduced hymns composed by English hymn writers to American hymnody. Lining out hymns was a common practice in poor white and slave communities who could not read or afford hymnbooks.
Step-by-step explanation:
The English Reformation had an impact on American hymnody by introducing hymns composed by English hymn writers such as Issac Watts, William Cowper, and Charles Wesley.
As Baptist, Methodist, and Presbyterian missionaries spread the gospel in the 18th and 19th centuries, they brought these hymns with them. In many poor white and slave communities, the practice of lining out hymns was taught to church congregations who could not read or afford hymnbooks, originating in England following the Protestant Reformation and spreading to Scotland and North America.
