I need the piano accom. part for the Haydn Flute Concerto in D Major. If anyone has it please email it to me at musickicksass88@yahoo.com

Thanks.

If you mean the score, well, why not buy it?
If you need a midi file to play along there are many sites in the web that offer hundreds/thousands of files. You may find yours, google it with patience

I agree with Jose, when I need music I buy it, I realize that's an old fashioned notion....
