Klaus Röder Born on 7 April 1948 in Stuttgart, married, 3 children. Violin lessons at the age of 10, later piano and guitar, from 1968 studies in ‘Bild und Ton’ engineering at the Hochschule Düsseldorf and composition with Milko Kelemen and Günther Becker, guitar with Dieter Kreidler at the Robert-Schumann-Hochschule Düsseldorf. During his studies he was a member of various bands (free jazz, rock, pop). 1972 to 2020 teacher for guitar at the music school in Langenfeld. Graduated with a diploma in electronic music composition. Since 1975 own studio in Solingen.

1970 Participation at the Darmstadt Summer Courses for New Music (scholarship).
1984 first experiments with computer music at the Institute for Communication Research and Phonetics at the University of Bonn with programmes for sound synthesis and sound analysis for the Kontron computer PSI 80.
Participation in courses on computer music: 1985 at the Groupe de musique expérimental de Bourges and 1988 at the Technical University of Berlin.
2002 Participation at the Stockhausen Courses in Kürten.

In addition to compositions for acoustic instruments (including ‘experimental’ instruments), he has written a large number of works of electroacoustic music (contemporary classical music), including 80 works for audio carriers (tape music).

1980 Award for Composition in Düsseldorf and Invitation to the ISCM World Music Days in Tel Aviv. In the same year he received a first prize for his composition ‘ Mr. Frankenstein’s’ Babies’ at the Concours international de musique électroacoustique de Bourges. Some years later he received in Bourges the ‘Euphones d’or’.
1988 1st prize at the Computer Music Courses Berlin for the composition ‘Kontra C’.

Klaus Röder was member of Kraftwerk in 1974 during the Autobahn LP.

Etüde für Klangwandler-Orchester (text from 1984) This piece represents an attempt to reproduce electronic music authentically. Loudspeakers are primarily designed to reproduce music or speech, not to produce their own sounds. On the contrary, a loudspeaker that produces additional tones or sounds, i.e. that distorts, is bad. The best loudspeaker is the one that is most faithful to the original, i.e. the one that can best imitate the original. The original can be either instrumental music or electroacoustically produced or processed music specifically designed for loudspeaker reproduction, as is the case with most light music. But the original can also be electronic serious music. Here, too, the aim is to reproduce tones, sounds and noises as they exist on the sound carrier (usually tape). A distinction must be made between music composed specifically for sound carriers (radio playback, records) and music intended for playback in the concert hall. In the case of the former, loudspeaker (or headphone) reproduction is the appropriate means, because the music was created for this purpose. With the latter, however, the performance over loudspeakers in the concert hall often seems like a reproduction, not an original performance, because it is merely the faithful reproduction of a tape. Nothing happens during the performance, and it is questionable whether the word performance is appropriate at all, since actually only what already exists is reproduced. For this reason, I am trying for the first time to use the so-called Echonic Sound Transducers II to create electronic music. Attached to certain objects, they create a sound spectrum that is determined by these objects. Since these are enamelled tin keys, the inherent resonances of these bowls, for example, are reproduced in an amplified way. Filling in water, inserting objects, etc. each drastically changes the characteristic of such a special loudspeaker, which deserves to be called a musical instrument, since tones, sounds and noises are produced with it during the performance – i.e. live. Although their origin comes from the tape, they only exist there in simple basic forms of vibration such as sine tone, impulse or noise, and in this form they are by no means the final music, but only the raw material to be formed, similar to the vibrating string on the violin or the vibrating column of air on the flute, which is also only made into music by being played by the musician. The difference to the traditional musical instrument is, among other things, that the latter demands a lot of concentration from the musician to play at the right time, whereas the player of the sound transducer instrument can fully concentrate on the interpretation of the music, i.e. on articulation, phrasing etc. The piece is performed by eight players according to the score. Since there is some freedom in the way of interpretation, the sonic experience is largely determined by the virtuosity of the performance and the interplay of the musicians. The composition is intended exclusively for such a performance. The vibrations present on the tape are not intended for reproduction via normal loudspeakers!
