Günther Rabl FAREWELL TEMPERED PIANO computer music, 42min, stereo, Rastenberg 1991 ODYSSEE FAREWELL TEMPERED PIANO Mit dem Wortspiel im Titel, das übrigens auch auf Deutsch funktioniert ('Lebwohl temperiertes Klavier'), ist keineswegs das Musikinstrument Klavier gemeint. Es bezieht sich vielmehr auf ein Tonsystem, das heutzutage - durch die industrielle Musikproduktion und Consumerelektronik - noch im hintersten Winkel der Welt unhinterfragt hingenommen wird. ODYSSEE Die Komposition führt mehrere Ebenen ein: eine Ebene der Erzählung, die von fernen Ereignissen berichtet und die tieferen zeitlichen Schichten, in denen die Erzählung plastische Gestalt annimmt. Beide Kompositionen sind Auftragsarbeiten im Rahmen des Projektes 'Austrian Soundscape' für den österreichischen Pavillon der EXPO'92 in Sevilla und wurden - zusammen mit Werken von Gottfried Martin und Dieter Kaufmann - über eine eigene Installation von 24 Lautsprechern sechs Monate lang täglich gespielt.

Günther Rabl FAREWELL TEMPERED PIANO Computer Music, 42 min, Stereo, Rastenberg, 1991 ODYSSEE (ODYSSEY) A commission for the Austrian Pavilion at the EXPO '92 in Seville FAREWELL TEMPERED PIANO The wordplay in the title, which incidentally also works in German (“Lebwohl temperiertes Klavier”), does not allude to the musical instrument of the piano at all. Rather, it refers to a sound system that today – through industrial music production and consumer electronics – is simply accepted unquestioningly even in the farthest corners of the globe. As a musician on a stringed instrument without frets (the contrabass in my case), one is inevitably confronted with the quality of “pure intervals.” However, not in the sense of ancient and medieval number mysticism, but in the sense of physical-acoustic reality instead. Musicology has occupied itself in the past centuries with the contradiction of the pure intervals to the desire to be able to return to the original tone after an arbitrary progression of intervals. Numerous tempered and untempered tunings were proposed by theoreticians and instrument makers, of which the 12-stage piano tuning is considered the ultima ratio. The purity of the intervals is foregone in favor of a secured scale of pitch levels. From the point of view of computer music, however, the question arises: What for? Who says we’ll ever have to come back to the same tone? The algorithm underlying this work is defined in such a way that a return – except for a few steps – is not possible. Harmonically, the development moves more and more away from the respective origin. This algorithm is a formula that determines the interval progression, but also the rhythmic structure and accentuation. Depending on which supply of possible intervals is given to the formula, characteristic short pieces emerge, which then find a natural end when there is no solution. Pieces could be generated endlessly in this manner by feeding the formula with ever-different interval combinations. I have selected some very distinctive ones for this collection. It starts with the usual intervals of the octave, fifth, fourth and a pure whole tone. Gradually, intervals based on higher prime numbers are added: the pure thirds, the “blue notes” with the proscribed seven, and so on. Towards the end, the interval supply is increased to dozens of possibilities, which surprisingly arise again as vital, music-making forms. Except for the 3 “toccatas” in between, which use the rushing of water as sound material, the basic sound is a single sample that I had generated somewhere along the way with my string model. The whole thing was originally intended as a sketch to test out the algorithm. Later, I wanted to recreate the pieces with more refined sound material. But when I had the finished collection in front of me, I knew: That’s it. Any enhancement towards nuanced tone and phrasing would ultimately only dilute the character of these pieces.
ODYSSEE (ODYSSEY) The composition introduces several levels: a level of narration that tells of distant events and the deeper temporal layers in which the narrative takes on a sculptural form. The top level (“monologues”) consists of excerpts of an endless algorithmic process that generates precisely this narrative style ad infinitum. All other pieces are completed algorithmic forms as in FAREWELL TEMPERED PIANO, but this time applied to flute motifs Martina Cizek had provided me with. Water rushing and a bell sound give additional colorations. Both compositions are works commissioned within the scope of the “Austrian Soundscape” project for the Austrian pavilion at the EXPO’92 in Seville and were – along with works by Gottfried Martin and Dieter Kaufmann – played daily for six months over a custom-made installation of 24 loudspeakers. Accordingly, the stereo panorama is designed so that the music develops a complex spatial effect through a wealth of different running times. |
