Haligweorc writes on Basic Disciplines for [Anglican] Liturgical Worship, Part II, but makes several generally-applicable points. I especially liked this bit:
Check the psalms. Does it really say, “Let the sea thunder and all that is in it; let the field be joyful and all that is therein. Then shall all the trees of the woods fold their branches over their trunks and just stand there stoically while everyone else is singing as if they’re too cool to join in (perhaps in a slightly ironic way)?”
as well as the comments on how choice of music (and, I might add, arrangement and amplification) “sabotage” the invitation to participate.
