Someone asked for the chords for this interesting melody. I've downloaded it from this website

http://ingeb.org/Lieder/indenaug.html

The MIDI on that site has an introduction (to get dancers onto the floor) and, I believe, a coda. I don't have time to match the words to the tune, but I believe that's what's going on. The coda ends with a bunch of G chords after the 16th notes. Then the tune repeats.

I could never play it as fast and with as many chord changes as they have on the site. Also, there are some pile-ups which may simply be mistakes. So I've been playing the song at my piano, and I have come up with simpler chords.

Keep in mind that the original in the key of G is too high to sing and that citrusy dissonances are common in old waltz tunes.
