Some of the psalm books were published without music, some with the melody only, and others in four-part harmony. The statement is frequently made that Calvinistic Protestantism approved only unison singing. The appearance of numerous books, complete with four voice parts, points to the contrary. It is true that Calvin at first encouraged unison singing only, regarding harmony more in the nature of amusement than the worship of God; but upon observing the effectiveness of singing in Germany, he soon changed his views and became more liberal in this respect. 9. English Hymnody. The youthful, courageous Isaac Watts, 1674-1748, an ardent dissenter, pioneered the movement which resulted in a flood of hymns and hymnbooks in the English churches. Watts was not satisfied with the psalm singing of his time, which by now had become formal and lifeless. Parts of the psalter, he pointed out, were obviously not written in the spirit of the Gospel. “By keeping too close to David,” he wrote in one of his Prefaces, “the vail of Moses is thrown over our hearts.” Watts removed that “vail,” Christianizing the psalms and composing during his lifetime more than 600 original hymns, expressing in the language of the time, the thoughts of the worshippers. Through his influence, his age, the 18th century, became the first age of hymn singing in England. John and Charles Wesley, following Watts, made enormous use of hymn singing in their evangelistic work, giving the movement for congregational singing a powerful impetus. Charles is said to have composed over 6,000 hymns. From the Wesleys onward through the 19th century, the hymn writers in England became numerous. The restrictive shackles of psalm singing had been broken and the creative urge to worship in new forms resulted in a vast number of original religious lyrics and the publication of hundreds of hymnbooks. The development can be summarized here only in outline form. English Hymnody in the Hymnary
