I have been playing this piece for a long time, with various instrument combinations. I cannot figure out who the composer is, even though I am pretty sure it is from the Baroque period.
If you want to listen to it, go to this forum

You will have to check it in the "Play For Us!" section of the forum. I name it "Baroque Anonymous" there.
I wonder if anybody knows the composer and the original instrumentation. Thank you.
