Delia had an exploratory encounter with Karlheinz Stockhausen.[1]

Pieces known by Delia

Electronic Study 2 (1954)[2]

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".[2]

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.[2]

This, presumably, is what is on Delia's Attic Tape "Stockhausen Study 2".

Gesang der Jünglinge (1955-56)[3]

Louis Niebur says that Delia admired[4] Karlheinz Stockhausen's piece Gesang der Jünglinge, described as "the first masterpiece of electronic music",[3] though he gives no source for this assertion.

Jonathan Harvey says that "the overall structure of Gesang der Jünglinge is remarkably like that of Electronic Study 2; both final sections combine and develop the ideas stated in the preceding sections."[3]
