No one likes to have to make rules, much less enforce them. But what if you could do it with humor, even getting your students to self-police? That just might be the end result when you use the round "We Shall Not" to make your disciplinary point. Set in a minor key with a dramatic string orchestra as a backdrop, it's the contrast between the accompaniment and the lyrical content that makes the tune amusing.
As usual, the second part is optional, but since this is written as a round, it is more fun when you use it. (from Music K-8, Vol. 20, No. 1)
