This week, the USCCB is taking a new look at the repertoire of music sung in Catholic churches across the country. You can see their Powerpoint presentation here.
Hopefully, a document better than Music in Catholic Worship (from 1972) will come out of their efforts; the USCCB is meeting to discuss the drafting of a new document. Jeffrey Tucker of the New Liturgical Movement also blogged on this last week.
Update: And they did nothing, thanks to His Excellency Most Reverend Donald W. Trautman (Bishop of Erie, PA), the outgoing president of the Bishop's Committee on the Liturgy. Under the leadership of His Excellency Most Reverend Arthur J. Serratelli (Bishop of Paterson, NJ), the committee will be renamed the Committee on Divine Worship, and, given Bishop Serratelli's track record, the CDW should really have a positive effect on fixing and strengthening the quality of the liturgy in the United States.
