Sequitur I (2008) for flute and live-electronics
Solomiya Moroz: flute / Karlheinz Essl: live-electronics
Recorded live on 23 Apr 2012 at Elak Wien


Sequitur is a series of compositions for various solo instruments and live-electronics which I started in 2008. Somehow it can be seen as a reference to Berio’s famous “Sequenze” cycle of solo pieces which focus on specific playing techniques of the respective instrument. Up to now I have finished more than a dozen pieces including orchestral instruments like flute and violin, but also for voice and more exotic ones such as electric guitar, toy piano and 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. Each piece can be performed by the player alone who just has to press a key on the computer keyboard whenever this is indicated in the score. The 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.
