The Congress of Vienna Waltz
Some time in the mid-1990s, I tracked down a copy of the music for that very pretty waltz choreographed by John Hertz. It was not available on CD at the time. I sampled the music from cassette, cleaned up the worst of the noise, and encoded the result as an MP3 file. I posted it here so dancers wanting to practice the choreography would have access to it in a format more practical than magnetic tape. If you download it, please send me a note so that I know my time was well spent.
The musicians who recorded this performance are unknown.
It has been suggested that the first two parts of the music are Swedish traditional pieces, but so far, I haven't found them anywhere outside of The Congress. The third and fourth parts are apparently from a tune by Ola Nilsson Lans, sometimes listed on recordings as Vals efter Ola Lans.
The dance is a modern creation, inspired by dances from Regency England, and has become very popular in vintage dance circles throughout California. If you're interested in learning it, I suggest contacting the Friends of the English Regency (southern California) or attending one of the Gaskell Ball classes (northern California).
