From the Form of Church Government, para. 17:

The Ordinances of Worship in a Particular Congregation

17. The ordinances in a single congregation are prayer, thanksgiving, and singing of Psalms, the word read (although there follow no immediate explication of what is read), the word expounded and applied, catechizing, the sacraments administered, collection made for the poor, dismissing the people with a blessing. In accordance with the simplicity and purity of worship provided for in the church's Basis of Union, the church's worship shall be without instrumental music, and only the Book of Psalms shall be used for singing in worship. The Authorized King James Version shall be the text used in the public reading of the word, and the Scottish Metrical Psalter the text for singing in worship.
