In the introduction the spectrum of the two polarities that will be heard throughout the piece (A and Eb) are displayed forcing the filter resonance of the synthesizers to self-oscillate and with an scordatura violin playing harmonics from both roots. The theme is performed on the violin (standard tuning) with accompaniment from the synthesizers. Variation#1 is like a violin cadenza on the theme. On Variation#2 the two synth performers play a repetitive reduction of the theme with a noisy texture electronic texture, generated by a random square LFO applied to amplification. Finally, on Variation#3 the 3 players perform 21 notes of the theme with the duration of each one being determined by chance, by 7 random wildcards that are put in front of the players during the performance with the durations (in seconds) of each note. The possible numbers are the first seven numbers of the Fibonacci sequence, wich are also the numbers of the partials from each root that are used throughout the piece.
