Southbound / Südwärts is the first part of a series of works based on an acoustic „gating“ system. The system consists of digital switches that control the amplification of the respective string instrument’s output signal. Thus, the system enables creating rhythmic shapes out of continuous instrument sounds. The technology of gating, otherwise primarily used by sound engineers in the studio, here is employed as an artistic strategy. The gating technique underlying ‘Southbound / Südwärts‘ is a fundamental element of Zaes‘ practice ever since. It informs a great number of his recent works as Zaes seeks to develop and to expand its possibilities.
Due to the long-term collaboration with violinist Katryn Hasler, ‘Southbound / Südwärts’ exhibits not only a technical and daring raw sound aesthetic, but also an exceptional score that only determines the rhythms and the forms of the piece, but leaves the choice of pitch to the instrument player.
Regarding structure and form, the piece deals in a reductionist way with the loop. Patterns of a single constant length are played by the instrument player and then get successively sampled and played back. The resulting effect makes audible the intense layering of violin and sine waves – each layer radically treated by the gating system – and renders the piece stark and spatial.
The piece, recorded featuring viola player Julia Purgina, has been published under the title "süden for julia" within the compilation CD "KOFOMI#14 FARBEN" by ein_klang_records, Vienna, in 2009: einklangrecords.com
