I remember back as a child, I grew up around a lot of musically enriched people. One person we knew had artwork in his house like freehand coal caricatures of jazz greats like Dizzy Gillespie and Louis Armstrong. He also had scores very much like this one. I always felt they were simply made for the artistic appeal; the use of the visual affects musical manuscripts, especially those of classical music, can include. I felt they weren't intended to be performed in any fashion but this piece, Faerie's Aire and Death Waltz (Page One & Page Two), appears to actually have a performance aspect to it.
It really is quite amazing. The silliness-for-silliness-sake style holds brilliance. This piece poses as a perfect example of how humor is a powerful vehicle for creativity.
Yes, this piece has actually been performed. How anyone could decipher anything playable out of the dynamic range, madcap time signatures, the endless string of pauses and other almost random - in many cases made up - artifacts boggles the mind. In the very least, it's far beyond my musical ability. Nonetheless, here's one example I found on YouTube. Musicians dressed up in silly costumes, big joke glasses and cow outfits. Every command placed on a cue card and, in most cases, acted out as a visual performance. One can only guess if this specific performance comes close to the composer's envision. The sheet music indicates everything was "arranged by accident" so maybe even he doesn't know.
