Tell me blackbird

 
Tell me blackbird why do you sing?  
I have asked many times before yet  
am no wiser . . . . . .you do not answer  
I don't think you know. perhaps    
to accuse you such is unfair,maybe  
I should climb your tree,or take  
a ladder to the tiles,see the view  
from which you sang today and  
yesterday,the day before,tomorrow  
and every other day that would be. l  
would be without you but less.Yes  
I'll take the ladder,sit upon the tiles  
and sing. Will you stay and listen?  
What shall I sing, a simple song?  
Extemporised as yours?  
Or take the violin, practice, as  
 you have done these thousand years  
until the notes fly pure above the leaves  
lost to all but memory, perhaps to know  
why you sang today,yesterday  
the day before and shall tomorrow
