I sing in the choir at church. (Well - I emit noise, anyway. It's not a choir that requires an audition, and my daughter is the director, so I'm in!)
And last Sunday, our excellent accompanist commented on the long stretch between the bass note and the tenor note... it was well over an octave, and she told us, "You tenors, I might have to sacrifice your note if I can't play both." A notorious smart-alek, Mark, piped up, "Can't you play one of the notes with your nose??"
I've been thinking about that.
Some of you old-timers might remember "suicide knobs" from the good old days. Back before power steering and automatic transmissions were widespread, a popular after-market accessory was a small rotating knob, which you could bolt to your car's steering wheel. It allowed easier one-handed steering, leaving the other hand free for alternate duties. They were sometimes called a "necker knob," or a "Brodie knob" after an actor/daredevil from yesteryear.
