Yeah, that's the video. You keep waiting for some kind of resolution, but there is none. After listening to it, I hear twelve-tone music in a whole new light. I know Bartok wrote quarter-tonal pieces, I can't find them, however.
I still haven't heard a true microtone piano, namely the 16th tone piano, which divides the octave into 96 equidistant tones. The 97 key Sauter microtone piano tonal span is only one octave from key #1 to Key #97! On this piano each half-step is subdivided into eight equal tones. That's eight tones in between the note B and the note C. I've yet to find any recording of it.
Are we in the Twilight Zone yet?
