The Westminster Directory of Public Worship (1645) nowhere mentions hymns or songs of man-made composition. To see it overwhelmingly demonstrated that ‘psalm’ in the Directory meant one of the 150 psalms of David, see Matthew Winzer’s, Westminster and Worship Examined: a Review of Nick Needham’s Essay…

Of Publick Prayer before the Sermon.
After reading of the word, (and singing of the psalm,) the minister who is to preach, is to endeavour to get his own and his hearers hearts to be rightly affected with their sins, that they, may all mourn in sense thereof before the Lord, and hunger and thirst after the grace of God in Jesus Christ, by proceeding to a more full confession of sin, with shame and holy confusion of face, and to call upon the Lord to this effect:
…
Of Prayer after Sermon.
…
The prayer ended, let a psalm be sung, if with conveniency it may be done. After which (unless some other ordinance of Christ, that concerneth the congregation at that time, be to follow) let the minister dismiss the congregation with a solemn blessing.
Of the Sanctification of the Lord’s Day.
…
That what time is vacant, between or after the solemn meetings of the congregation in publick, be spent in reading, meditation, repetition of sermons; especially by calling their families to an account of what they have heard, and catechising of them, holy conferences, prayer for a blessing upon the publick ordinances, singing of psalms, visiting the sick, relieving the poor, and such like duties of piety, charity, and mercy, accounting the sabbath a delight.
Concerning Publick Solemn Fasting.
…
So large a portion of the day as conveniently may be, is to be spent in publick reading and preaching of the word, with singing of psalms, fit to quicken affections suitable to such a duty: but especially in prayer, to this or the like effect:
Concerning the Observation of Days of Publick Thanksgiving.
…
And, because singing of psalms is of all other the most proper ordinance for expressing of joy and thanksgiving, let some pertinent psalm or psalms be sung for that purpose, before or after the reading of some portion of the word suitable to the present business.
…
The sermon ended, let him not only pray, as at other times after preaching is directed, with remembrance of the necessities of the Church, King, and State, (if before the sermon they were omitted,) but enlarge himself in due and solemn thanksgiving for former mercies and deliverances; but more especially for that which at the present calls them together to give thanks: with humble petition for the continuance and renewing of God’s wonted mercies, as need shall be, and for sanctifying grace to make a right use thereof. And so, having sung another psalm, suitable to the mercy, let him dismiss the congregation with a blessing, that they may have some convenient time for their repast and refreshing.
Of Singing of Psalms.
It is the duty of Christians to praise God publickly, by singing of psalms together in the congregation, and also privately in the family.
In singing of psalms, the voice is to be tunably and gravely ordered; but the chief care must be to sing with understanding, and with grace in the heart, making melody unto the Lord.
That the whole congregation may join herein, every one that can read is to have a psalm book; and all others, not disabled by age or otherwise, are to be exhorted to learn to read. But 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.
