Sequitur IIIb (2008/2018)for viola and live-electronics

New Music by Karlheinz Essl

Recorded live at INTONAZIONE festival on 20 Sep 2019 at Eremo Santa Caterina in Rio nell'Elba, performed by Rafał Zalech (viola & live-electronics)during a dance performance of Andrea Nagl. Mixed and produced by Karlheinz Essl. 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. 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 become 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.
