Olga Neuwirth, »Notizen zu Hooloomooloo, 1996/97«, in: Olga Neuwirth - zwischen den Stuehlen: A twilight-song auf der Suche nach dem fernen Klang, (ed.) Stefan Drees (Salzburg , Wien u.a.: Pustet, 2008)

»I restricted myself to one note (flattened Eβ) on the well-broken-in ondes Martenot (as a semielectronic instrument, it had a completely different sound quality than that of the traditional ensemble), which slowly changes timbre and progressively moves through various registers — that is, through the sound space — before returning to the overtoneless Eβ. Around this ’ground plan’ that runs through the whole piece, three ensembles comprised of different instruments move around, playing with foreground and background, analogous to the Hooloomooloo triptych. These three ensembles constitute three coequal variations. Each one of them somehow has its own independent statement and the same value as the others in relation to the ’ground plan,’ but only in its entirety is the version complete.«
