Sequitur XIV was written for the Hamburg-based pianist and performer Jennifer Hymer and sets the thumb piano in focus. This instrument, named ‘Mbira’ in Africa, was discovered in the middle of the 20th Century from the British ethnomusicologist Hugh Tracey, who developed out of it a standardized western instrument named ‘kalimba’, and let it be produced industrially. In contrast to the African original, this western new construction is tuned diatonically.

First I tried to approach the instrument like a child in that I pushed away all knowledge about the high art of Mbira-practice to the side. What did I see before me? A trapezoidal shaped wooden box with metal blades of differing lengths that were fastened over a sound hole in the middle. After I examined the sound possibilities of the kalimba’s body through rubbing, scratching and knocking, I attached a contact microphone to its surface and sent the sounds through the same computer program that I had developed for the other “Sequitur” compositions. Suddenly everything became enchanted: the canonic layering of my knocking and scraping noises compressed themselves into a polyrhythmic layering and I felt myself being transported to the south of Africa where the African musicians play this instrument in ensemble and thereby produce a highly complex polyphony which the Viennese musicologist Gerhard Kubik described as “inherent patterns.”

Only later I dedicated myself to the metal tines and through the help of live electronic manipulation found means and ways to dig out an ongoing diatonic. After many months of free experimenting, I was finally able to write a concisely written score for Jennifer Hymer, which turned my summing-ups of this instrument into a sound journey.

Sequitur XIV (2009) for kalimba and live-electronics

Electroacoustic Violist, Drone Composer
Boston -> Brooklyn -> Asheville

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)
