Jim Jordan has some advice on how a pastor should introduce new hymns and psalms to his congregation. In his Rite Reasons No. 19 he writes:
To teach new psalms and hymns, you need someone with a strong voice, preferably a man because the male voice is more powerful. (Since this involves teaching/training in the Word, it may be inappropriate for a woman to take this role anyway; but if the ox is in the ditch, so to speak, I don’t think it would be wrong to use a woman here.)
Have the leader sing through the first stanza. Then have him sing each line and the congregation sing it after him. If there are hard lines, do them twice. Then have the congregation sing the whole first stanza, and then go back and do the whole psalm or hymn. Use it again for a couple of weeks, so that the congregation becomes familiar with it.
