Separating voice from music

I have a WMA file that someone recorded for me. The person played a piano and sang a song I wrote. Is there any way that I can

remove the piano music from the song part? I would like to have just the person singing the song left on the file, and be able to

remove the piano music in the background. Is this possible?

Thanks for any help.

If both the piano and vocal were recorded as one track, I don’t think there is any way to separate them.

Unless they were inputted on separate channels (left and right) .....
