THE ACCEPTANCE OF THE THOROUGHBASS

Okay, today's virus-poem was engendered by the blind random method. The book was Harvard Concise Dictionary of Music, page 454. The line I landed on:

THE ACCEPTANCE OF THE THOROUGHBASS 

Alas poor Bass
before becoming thorough
she was a dilettante.
Nobody knew her sorrow,
the reason she was so gaunt. 

She suffered from insomnia,
that's right, she couldn't sleep,
then she met the guru Omnia
who said: stop counting sheep,
count Oms instead, one at a time,
I promise you'll be fine.

That's how Bass became thorough,
now accepted in every borough.
The moral of this story, plain to see,
better thorough than flibbertigibbety.
