Dona Nobis Pacem is a favourite for group singing. We've sung at assorted social gatherings, and Christine led the whole hall in singing it as a round at the Bloth.
Local convention for singing this one:
- Sing once through in unison, all three lines
- Split into three parts, sing twice through (adding voices with each entry at the beginning, dropping them out at the end).
- As the last group sings their last line: they sing alone for the first half ('Dona nobis pacem'), then everyone else joins in, very quietly on "dona nobis", swelling on "pacem".
There are midis with Cecilia's song book.
There are many recordings on YouTube
There is sheet music, and a little history, on the wikipedia page. It's also in the Big Lochac Snogbook (pdf, p 29), and Cecilia's song book.
