Psalmody was little more in favour than the gilded pipes of the organ. The Westminster Directory for Public Worship, adopted by the General Assembly in 1645, recommends that "for the present, where many in the congregation cannot read, it is convenient that the minister, or some other fit person appointed by him and the other ruling officers, do read the psalm, line by line, before the singing thereof." Before this time, in 1642, there had been much controversy in the western Lowlands concerning the singing of the doxology at the end of a psalm, a practice which was popularly regarded as a commandment of men, not to be accepted as a divine ordinance. The General Assembly, in 1643, took the matter into consideration, and ordered the dispute to be dropped. In 1649, however, the subject was again before the Assembly, which then resolved that the singing of the doxology should be discontinued. In 1647, a committee was named by the General Assembly to examine and revise Rous's paraphrase of the Psalms, and Zachary Boyd was requested to make a metrical version of the other Biblical songs; but nothing was done in the latter direction, probably due to the desire for uniformity with the Presbyterian Church in England, and in 1650 the present metrical version was printed for use in public worship, without the addition of any hymns or paraphrases. Nothing further was done for the improvement of congregational singing for more than half a century. The question of instrumental music was revived in 1687, by the erection in the Royal Chapel at Holyrood, by order of James II., of a large and magnificent organ, which was regarded as a step towards the introduction of the Romish service. So convinced were the people of this that the clergy of even the Episcopal churches discontinued the use of the organ in public worship. In the following year, when James had abdicated, and the fear of Popish devices had become allayed, the mob of Edinburgh testified to the national joy, and at the same time indulged their latent propensity to mischief by breaking down the organ and burning the materials.
