Electronic Study 2 is a piece by Karlheinz Stockhausen created in 1954.[1]
In it, "he selects quite a constricted range of material, the proceeds to cover it totally, to use up all the possibilities that the imagination considers worth while".[1]
Studie 2 is eighty-one sine tones pitched along an exponential frequency scale which spans just over seven octaves. The steps are all perceived as equal and are a little over 1/16th of an octave in size. [...] The most significant thing about these intervals chosen by the 25th root of 5 is that no octaves occur. The lowest frequency is 100 c.p.s, and no multiple of 100 by any whole number occurs throughout the scale.[1]
This, presumably, is what is on Delia's Attic Tape "Stockhausen Study 2".
