In fifth grade, our class chewed up and spit out a revolving door of music teachers. Our first victim was Mr. Alexander, a tall Asian man with ruthless expectations. He demanded “tone, tone, semi-tone” until we could hear it no more and locked him in the vault, which happened to be the music office. He got his revenge by leaving kids at the side of the road on a field trip, but by then it was too late- Mrs. Hyde had arrived.
Mrs. Hyde/Jekyll stamped her heels with such enthusiasm that eventually, one flew off and struck a student in the eye. Given our campaign (in progress) to record (in secret) her violence to use against her, the principal had no choice but to introduce Mr. Gilbert.
The old man disappeared on an alleged cross-country motorcycle trip. This, of course, when we had just begun to like him.
