Upon receiving the teacher's evaluation sheet of my demonstration speech, I was pleased to see my primer on how to play the bass received an A. The only negative comment on the form was next to the category, 'Explained reason for demonstration.' The teacher wrote, "Needed to be more clear about this...Why should we want to learn to play the bass?" I thought I'd provided sufficient justification during my speech. I told the class, "When you learn to play the bass, you have a greater understanding of how music is put together. So often, people pay most of their attention to a tune's melody. When you play the bass, however, you'll have a greater understanding of what's supporting the melody and keeping the rhythm going."
Oh, well...An A is still an A. Besides, does there really need to be a reason when it's a class assignment? Wasn't "because it's yummy" a sufficient reason for another student to show how pound cake is made?
