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 composition 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.

Inertia is the first of a set of works by the composer 
utilizing a system he developed called “monodies”. In this system Hosseini attempts to bring into relief the distinct function of the aggregate of all individual lines of the music - heard as a single horizontal complex.

Imbedded within this rather experimental approach is a set of time-honored principles derived from various oriental traditions - perhaps the most salient example of which can be found in the “dastgah” music system belonging to Persian music traditions. 

Inertia contains an emergent form approximating both the common principles employed in the spontaneous compositional procedures of oriental music and practiced today in the field of audio synthesis.

Itself (2012) for orchestra

Recorded live on 9 June 2010 at the Essl Museum, Klosterneuburg by Tzenka Dianova (piano) and Karlheinz Essl (live-electronics).

Karlheinz Essl's “Sequitur XIII” (2009/2013) for extended piano and live electronics is an innovative work in which the piano has been transformed into a super instrument thanks to a computer-based algorithmic system. Turning the relatively simple instrumental material into an orchestral entity through various real-time harmonic and spectral alterations, the piece multiplies the functions of the original instruments by recording the musicians' performance and playing it together with its modified version (Maria Kallionpää, 2014)

Sequitur XIII (2009) - for extended piano and live-electronics

Recorded by Anton Lukoszevieze (cello) and Karlheinz Essl (live-electronics) at the University of East Anglia (Norwich, UK)on 18 Sep 2008.

The Sequitur cycle consists of 14 different compositions for various solo instruments and live-electronics. 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 composition 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.

Sequitur II (2008) - for clarinet and live-electronics

First reading of Karlheinz Essl's Sequitur I piece with Karlheinz on electronics.

Sequitur-I 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.

Sequitur IIIb

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

Born 1960 in Vienna. Austrian composer, improviser and performer. He studied composition with Friedrich Cerha and musicology in Vienna. Besides writing experimental instrumental music, he performs on his own electronic instrument m@ze°2, develops software environments for computer-aided composition and creates generative sound and video environments. Since 2007 professor of composition for electro-acoustic and experimental music at the University of Music in Vienna.

Karlheinz Essl performs on a laptop computer that he has transformed into a live electronic musical instrument. The result is exciting and musical. You just won't hear these sounds anywhere else. He performs solo and in duets and trios, responding with sensitivity to fellow musicians, producing fascinating sound transformations, creating spontaneous surprises, and moving quickly from loops to cacophony to tiny clips of vocal sounds to all kinds of textures and ideas. He does all this with his m@ze°2(Modular Algorithmic Zound Environment) performance software. (Joel Chadabe, CDeMusic, Januar 2002)
