Are you looking for an excerpt from an opera to sing? or are you going to find another piece of music - folk, choral, etc.?
I really like how you're providing routine and structure to a very organic and creative experience. Since this sounds new for the students, this approach might help in their overall focus.

Amanda, Mubeen and Sona - how did this first session go from your perspective? What were some of the comments from the students the day after the session?
