Sequitur IV (2008) for cello and live-electronics
Anton Lukoszevieze (cello) & Karlheinz Essl (live-electronics)
Recorded and produced at University of East Anglia, Norwich 17-18 Sep 2008


Sequitur is a series of 14 compositions for various solo instruments and live-electronics written for outstanding soloists. Somehow it can be seen as a reference to Luciano Berio's famous Sequenze cycle of solo pieces which focus on specific playing techniques of the respective instrument including orchestral instrument. Essl's Sequitur cycle includes pieces for orchestral instruments like flute and violin, but also for voice, electric guitar, toy piano or kalimba.

All Sequitur compositions use a software written in MaxMSP which creates an electronic accompaniment from the instrument’s live input; the player is confronted with his own playing, and this creates a situation like moving in a house of mirrors where the identities becomes blurred.

The Sequitur software generates a complex canon on the fly, the temporal structure and density of which being controlled by random operations. This yields different results every time the piece is performed. Although following a precisely notated score, there is always a good portion of surprise for the musician which emphasizes his awareness and attentiveness.
