Have You Heard the Sound of Dark Blue?

Have you heard the sound of dark blue?
I'm sure you have.
Have you heard tears when losing a soccer game?
   The sound of dying or whining?
   A piano playing the blues?
Have you heard the sound of a willow 
   moaning in the wind?
   The plop of a scoop of ice cream from a baby's cone?
If you could, or if you do,
That is the sound of dark blue.
