Origami is my first attempt to explore this instrument thoroughly. The accordion captivates with its sonority, but I wanted to be enticed by it in more than just a sensual way. For me, the accordion contains two worlds, as the button arrangements on the two sides of the instrument show: The diatonic chords on one side, arranged in a circle of fifths, come from a world »before contemporary music«. The chromatically arranged tones on the other side, in contrast, offer every conceivable possibility of sounding together, which accommodates abstract, almost algorithmic thinking. I have tried to combine these two worlds: The juxtaposed, pre-contemporary chords lose their tonal characters through a flowing and overlapping linkage and become an undulating harmonic kaleidoscope. The other, symmetrical world is represented by a chord logic and linkage based primarily on common »edges« of adjacent chords. I connect both this chord logic and the true physiology of the instrument in my idea of "folding". From here it is only a step to the art of folding, to origami, which has always fascinated me by its deliberate material limitation and simplicity. (2015)
