This is a book of my favorite rounds, suitable for running off enough copies for a singing party.
The asterisks indicate where to come in. The second voice should enter when the first voice reaches the asterisk, and so on. When counting is important (e.g. in Schickele's Dona Nobis), I've marked subsequent entrances as well, so that the third voice should come in when the second voice is at the first asterisk and the first voice is at the second asterisk.
I tried to pitch the rounds where both everyone can sing them and they're not too hard to read. In general I erred on the side of pitching low; ranges typically lie in G4-D5. These pitches were not very extensively tested.
All the rounds live in one large Lilypond file, in alphabetical order.
See book.ly for more details.
The book can be built with a simple lilypond book.ly command.
You will need a Lilypond version at least 2.14.2.
