Parishes accustomed to using a single source for Responsorial Psalms have an opportunity this year to widen their options. This year is Cycle B, the Year of Mark, the shortest Gospel. During the summertime (July 29-August 26 this year), the Gospel is taken from the Bread of Life discourse in John chapter 6.
For three of those weeks, in a row, we will sing the classic Eucharistic Psalm 34, with the refrain Taste and see the goodness of the Lord.
This would be an opportune moment to seek out alternatives to the usual Psalm fare. The options are almost unlimited, and include new settings by CMAA composers and others, too many to mention here (but I hope some will be added in the combox).
