Semaphor is a spatial sound composition and the title refers to a visual telegraphy system transmitting information from one tower to another. It was developed together with the German composer and sound artist Gerriet K. Sharma for two pioneering instruments: the Helder-Jahn Tenor and the Icosahedral loudspeaker. This is a unique sound projecting instrument developed at the Institute of electronic music and acoustics in Graz. The musical material I am using here on the Helder-Jahn Tenor is very much inspired by Gerriet’s electronic music. It is literally turning the usual sound world of the recorder upside down, including for example very soft pitches in the third octave, harmonic overblows and granular tones.
