So, I was just randomly searching through my history on my computer (yeah, I know, there are MUCH better things to be doing...) anyways... I found this site, Chant Cafe, and a British guy has created a short, 6 lesson unit on teaching chant in private schools. It is COMPLETELY free and he has a great way of putting chant in context and comparing it to other forms of music that children are used to hearing. Since he is from England, his "pop music" is a bit different then American style but most of his ideas will work great!
I just LOVE this short recording he has demonstrating the various ways (the incorrect and then the correct) of singing a chant: Singing Amen and Alleluia (pop like...)
Enjoy! I am just soooooo excited that I found this! The man who created this is entertaining and he has great activities to make learning about and developing a love of chant, fun!
The internet is my friend once again! :)
