This psalm is used for Easter Vigil, Pentecost and as an ordinary psalm with the verses varying with each celebration. Paul Mason has provided all the variations in his setting found in Psalms for All Time.
The response is singable by the assembly despite the surfeit of triplets. He worries that each verse has a different tune, so recommends a cantor. They do have the same basic structure though, so just possibly could be sung through by the assembly. It is really is a delightful tune.
The text is in your missal or as set by Kate Keefe.
My backing is the common psalm and Pentecost setting.
