I recently found this article on wikipedia about lists of musical works in unusual time signatures and the first unusual time signature is (1/√π)/√⅔. I looked up the piece that was listed as having that time signature which was Conlon Nancarrow's Study for Player Piano 41a and listened to it and could not begin to count it at all.
So is the time signature actually useful and if it is, is there a specific name for time signatures like this?
