Here is the neume song, as developed by Matt Williams and posted on the MusicaSacra forum. It is really helpful because reading neumes requires (or at least is assisted by) and completely new vocabulary that can be extremely intimidating for beginnings. I know that it seem to take me years to be able to use all these terms as if they had real meaning. But once you learn them, rehearsal becomes much easier.
You will really enjoy listening to this. The director is pointing at the chalk board as they go through the song.
