Can fish understand human music?

 Can fish understand human music?

"Our  worlds apart, sea and land

across a thin transparent sand." avr 

Dr Abe V Rotor

   Author plays violin before a home aquarium of Oscar fish.  

I touch your senses with the violin

     in a variety of tune and melody; 

I touch your world, and yours with mine,

     together we make a fantasy.

I wonder what song you sing in water

     if ever heard outside your realm;

The bleating lamb in Beethoven's ear,

     thunder and the bubbling stream.

Do you  also sing a Brahms's lullaby

     or San Pedro's Ugoy sa Duyan?

March with Mendelssohn's graduation, 

     for real or just for the fun?  

My fish do not answer, they are dumb;

     Or I can't hear and understand;

For worlds apart we are, sea and land

     across a thin transparent sand. ~
