Sound of Silence?

I can scarcely believe my eyes. Chris Pasles wrote a 1 1/2-page article (April 16) on the ballet “Billy the Kid” with no mention of the composer, without whose music the work would simply be a bunch of folk tripping around the stage with only the sounds of their feet to accompany them.

Mr. Pasles, you are now to write “Aaron Copland” on the blackboard 1,000 times. And after you are done, if you are truly repentant, I grant you this wonderful reward: You may listen to the music.
