One of your great objects should be to induce all the congregation to join in the singing. Your minister should help you in this, and his exhortations and example will be a great assistance to you; but still as the Lord’s servant in the department of sacred song you must not rely on others, but put forth your own exertions. Not only ought all the worshippers to sing, but each one should sing praises with understanding, and as David says, “play skilfully” unto the Lord. This cannot be effected except by instructing the people in public psalmody. Is it not your duty to institute classes for young and old? Might you not thus most effectually serve the church, and please the Lord? The method of Mr. Curwen, and the use of his Sol-fa Notation, will much aid you in breaking ground, and you can in after years either keep to the new method, or turn to the old notation as may seem best to you. Thousands have learned to sing who were hopelessly silent until the sol-fa system was set on foot. The institution of singers, as a separate order, is an evil, a growing evil, and ought to be abated and abolished; and the instruction of the entire congregation is the readiest, surest, and most scriptural mode of curing it. A band of godless men and women will often instal themselves in a conspicuous part of the chapel, and monopolise the singing to the grief of the pastor, the injury of the church, and the scandal of public worship; or else one man, with a miserable voice, will drag a miserable few after him in a successful attempt to make psalms and hymns hideous, or dolorous. Teach the lads and lasses, and their seniors, to run up and down the Sol-fa Modulator, and drill them in a few good, solid, thoroughly musical tunes, and you, O sons of Asaph, shall earn to yourself a good degree.
