You're the director of a high school jazz band. The score for "The Flintstones" theme calls for the band to shout, "Wilma!" in unison near the end of the piece. Do you perform the piece as written, or do you ask one person who can shout, "Wilma!" with full commitment to carry it off?
My director took the latter approach, and it was the right call. Will, the saxophonist, belted it out with the right volume and inflection each time. With a voice that's best suited for Classical and late night jazz shows, I'm sure I wouldn't have done that half as well.
