Thanks everyone, for the responses and the woadlinks. I never cease to marvel at the amount of knowledge that Mudcatters have and at their kindness in sharing it. (Even you magpie enthusiasts.) Now I can give the song a German title which could be used in the future to research the piece. I'll also keep a record of the lyrics.

I doubt if we will be using the lyrics, even though two of us know German. We are an instrumental group mostly.

In addition, the music sounds like a sprightly Renaissance dance, while the words sound like a medieval exhalation of courtly love. As I'm sure you are aware, courtly love was always doomed.

The piece has four parts, and we shall be getting out the recorders for it. I think I will start a new thread on how to do this kind of thing.
