WDR Electronic Music Studio in 1966

During the 1950s and late 1960s before the advent of affordable electronic instruments, the only organisations that could afford the cost of the equipment and space for dedicated electronic music studios were generally large educational establishments such as Columbia University (USA) or as in this case, national broadcasters such as the state run Westdeutscher Rundfunk (WDR) in Cologne – at the time the largest and wealthiest broadcaster in West Germany. The benefit for these organisations was, on one hand to have a local resource for electronic music and sound effects to use in broadcasting but also, for ‘nationalistic’ reasons; to be see as liberally progressive and technologically advanced. Electronic Music composers remained reliant on their patronage until modular synthesisers became available in the late 1960s.

The Electronic Music Studio at Westdeutscher Rundfunk (WDR) in Cologne was founded by the composers Werner Meyer-Eppler, Robert Beyer, and Herbert Eimert (the studios first director) and was based on Meyer-Eppler’s ideas outlined in his 1949 book ‘Elektronische Klangerzeugung: Elektronische Musik und Synthetische Sprache’. This thesis defined the ongoing theoretical character of the studio as being based around electronically synthesised sound – in sharp contrast to Schaeffer’s musique concrète acoustic approach at GRN in Paris.

WDR is seen as the ‘Mother of all Electronic Music Studios’ because it quickly became a meeting place and forum for an international group of avant-garde composers including Ernst Krenek (Austria/USA), György Ligeti (Hungary), Franco Evangelisti (Italy), Cornelius Cardew (England), Mauricio Kagel (Argentina) and Nam June Paik (Korea) and Gottfried Michael Koenig who became the technical assistant at WDR and helped many composers create their pieces as well as writing many key pieces of electronic music at WDR (Klangfiguren II (1955), Essay (1957) and Terminus I (1962)). The pioneering work of previous composers has been somewhat overshadowed by the arrival of Karlheinz Stockhausen at WDR (who succeeded Eimert as director in 1962) in 1953 with pieces such as ‘Gesang der Junglinge‘ and Kontakte (1960) and Hymnen (1967) which became landmark works within the electronic music oeuvre.

The studio was originally equipped with a modified Trautonium by Dr Friedrich Trautwein modified to Meyer-Eppler’s specification called the Elektronische Monochord and  with a Melochord by Harald Bode  . As well as these instruments the studio consisted of:

  • Signal generators: sine , rectangular, sawtooth and noise
  • Filters: octave, third, radio drama (W49) filters.
  • Pulse generator
  • Ring Modulator
  • Oscilloscope
  • Rotary speaker for recording spatial sounds
  • Echo and reverb chambers: the reverb chamber being a large empty room where sounds could be played through speakers and re-recorded with the room ambience added.
  • Sixteen channel (2 X 8 channel) audio mixer
  • Patchbay to route modules
  • Tape Machines: several mono, 2-track and one 4-track (one of the earliest 4-track recorders made) tape recorders and a ‘Springer’ variable speed tape recorder with a rotating 6-fold playback head.

The equipment of the studio was updated to Stockhausen’s specifications in early 1970s to include what by then was standard voltage controlled modular synthesisers, including a large customised EMS Synthi 100. WDR studio remained in use until  2000 when it was closed though some of the original equipment was saved from destruction and is now stored in the basement of the WDR building in Cologne, Germany.

The ‘Aetherwellengeige’ was one of many instruments inspired by Leon Termen’s Theremin using the same heterodyning principle and body capacitance to generate a variable tone from two thryatron vacuum tubes (other instruments were the Sonar (1933) , Neo Violena (1927), Electronde (1927), Emicon (1932) and Croix Sonore (1929) amongst others) . This version was built by the amateur electronic engineer and musician Erich Zitzmann-Zirini in Berlin in 1934 after he had witnessed the Berlin Philharmonic Orchestra using Termen’s Theremin in 1927. Zitzmann-Zirini appeared with his instrument in the 1934 Funkaustellung ‘Orchestra of the Future’

The ‘Subharchord’, Gerhard Steinke & Ernst Schreiber , Germany (DDR), 1960

subharchord-studio-adlershof

In the late 1950′s the East German government decided that it needed to develop an ability to produce electronic music for film and TV for ‘Eastern block’ media as well as provide a platform ‘serious’ modern electronic music to compete with the likes of WDR Electronic Music Studio in west Germany. The result of this was the foundation of the first East European electronic music studio under the auspices of the East German National Radio (RFZ) in 1956 (and closed in 1970). The studio was called the “Labor für Akustisch-Musikalische Grenzprobleme” ( laboratory for problems at the border of acoustics/music ) , and in 1960 the ‘Subharchord’ was created as the centrepiece of the Laboratory.

The laboratory was founded in East Berlin in 1956. Gerhard Steinke, a young sound engineer who became its director, was tasked with research and development into stereo-sound and electronic sound generation. Countries all of over Europe were running similar programmes at the time, many of which were visited by Steinke in the years before East Germans were subject to travel restrictions. In 1961, a team headed by Ernst Schreiber, who was latter credited as the inventor of the Subharchord, completed work on the instrument:

While I was working as a sound engineer with the Dresden radio station, I heard of and found numerous tape recordings of Oskar Sala’s compositions for Trautonium, music that I had listened to on the radio while doing my homework, in the programs transmitted by the Weimar and Leipzig stations attached to the Dresden station, and above all in the sound archives. These unusual sounds were often used for the stations’ own programs, and even for advertising. However, what finally set me going was working with the conductor Hermann Scherchen, with whom I made a recording of Bach’s Kunst der Fuge in February 1949 in the Dresden Broadcasting Hall (the former reception hall of the German Hygiene Museum). In conversation with the conductor, it became apparent that Scherchen had long been with the radio and had already worked together with Trautwein, Hindemith and Sala around 1930.

The Düsseldorf Funkausstellung 1953 was the occasion of the first presentation of an electronic organ (Polychord), which was bought by the enthusiastic Berlin chief engineer at the radio station, despite our objections to the lack of transients and our opinion that we could make something much better ourselves. At the same time, the first studio for electronic music had been set up in the Cologne Funkhaus, with a new trautonium by Trautwein, the monochord. In 1955, in the instrument warehouse of the Berlin radio station, I unearthed the surviving parts of a quartet trautonium commissioned by Sala for the station in 1948 and that didn’t really work properly; even Sala’s visit to the laboratory failed to bring life into the instrument. But we were now more than just curious, and announced to Sala that we would develop our own much more modern device … Sala laughed jovially, patted me on the shoulder in commiseration, and went on giving concerts and producing film music with his mixture trautonium.

However, we were able to convince our chief engineer to set up a “Laboratory for problems at the interface of acoustics and music,” and recruited the resourceful television engineer and organ lover Ernst Schreiber. The work on the development began in April 1959. It almost collapsed when the Ministry of Culture objected that subharmonic sounds were a musical fiction since subharmonics did not exist in nature. … However, we were able to prove their existence by dividing saw-tooth sounds into a number of sub-oscillations, and were allowed to start. We were not allowed to develop the organ we had planned, mainly because Dessau had, at my lecture in the Academy of Arts on the presentation of a Polychord electronic organ, complained that such bombastic sounds with such a strong vibrato were more appropriate in a brothel, while the sounds of the trautonium were capable of inspiring the composer’s creativity. However, this wary ministerial representative soon disappeared off to the West, and we cheerfully worked on in the laboratory.

A first subharchord was ready in 1961, and was immediately welcomed with enthusiasm by the composer Addy Kurth from the field of cartoon films and by others in radio and television. We were now able to produce mixture compositions in a laboratory studio, pursue the further development of the instrument and later begin series production. The first marionette cartoon to be accompanied by the subharchord, The Race, was a huge success. We had maintained our contacts with Scherchen over the years and on 9 July 1961, shortly before the unexpected construction of the Berlin Wall, Dessau, who had always supported our development work, Scherchen and I met in the West Berlin Hotel Kempinski to discuss the prototype – although Dessau remained critical of the lack of a second manual, which he had always insisted on.

The development and series production, and the many recordings made at the same time in the laboratory studio, led to the creation of the subharchord II by 1969. Unfortunately, Khrushchev had condemned electronic music as a “cacophony” that was inappropriate to “socialist realism,” which meant that the studio and any further research were abandoned. Nevertheless, a few instruments survived, and two were reconstructed in 2005 and 2007. They are now being used for new creative works.”

The Subharchord’s history dates back to  pre-WWII exploration of ‘subharmonic’ synthesis of Dr Freidrich Trautwein’s  Trautonium and Oskar Sala’s Mixturtrautonium. These instruments uniquely used a technique of octave dividing sub-harmonic frequencies to modulate a synthesised tone creating a wide range of complex effects and sounds. Unlike the Trautonium family however, the Subharchord was less focussed on micro-tonal tuning and deployed a standard keyboard manual in stead of a sliding scale wire resistor.

Like it’s western counterpart, The Trautonium, the Subharchord was used extensively in film soundtracks and TV production throughout the Eastern block during the sixties and seventies; Karl-Ernst Sasse, former conductor of the DEFA (East German Film Company) Symphony Orchestra, worked with the subharchord in Dresden on the soundtracks of cult science fiction classics, such as ‘Signale’ ( a popular eastern block ‘Star Trek’ series). The subharchord was also used for many of the DEFA’s cartoons. Other composition from the studio include Der faule Zauberer (Kurth, 1963); Amarillo Luna (Kubiczek, 1963); Quartet für elektronische Klänge (Wehding, 1963); Variationen (Hohensee, 1965); Zoologischer Garten (Rzewski, 1965)

Later developments of Freidrich Trautwein’s original  Trautonium were continued by the Trautonium virtuoso and composer Oskar Sala. In 1936, Sala christened his first instrument the ‘Rundfunktrautonium’ (‘Radio-Trautonium’) and also developed a concert version, the “Konzerttrautonium”. After the end of the Second World War the instrument was re-named the ‘Mixturtrautonium’ but all were essentially developments of the original subtractive synthesis principles of the Trautonium.

The essential design principles of the Trautonium were retained by Sala; sound production on the basis of sub-harmonic ‘mixture’, and the method of playing with two string manuals. The latter are made of wire-covered catgut strings which act as variable resistors. according to the position at which they are pressed againts the contact rail beneath them, they control the frequencies of the electronic sound generators. when the finger glides over the string a continuous glissando results over the entire tonal region which has just been tuned up. Micro-tonal intervals could be produced on the Mixturtrautonium. To ensure accurate contact with the notes leather covered sprung and moveable metal tongues are added to each string.  Unlike with a vibrating string, the gradation of the electrical-resistant string manual is linear and not exponential so that all octave have the same finger range.

The 1948 post-war Mixturtrautonium was a polyphonic version of the original Trautonium, generating sound from two AEG Thoraton tubes with a 3 ½ octave range (which could be extended with an octave switch). The instrument could also be controlled with a foot pedal that not only allowed variation in volume but also with a lateral foot movement, select three different sets of sub-harmonics. The Sub-harmonic ‘mixture’ technique basically used un-natural low frequency harmonics to modulate a sawtooth signal creating complex harmonic ‘mixtures’ which could be further coloured with noise generators, mixers, an envelope controller and a frequency shifter.

Mixturtrautonium

During the pre-war period, the ”Rundfunktrautonium’ was used extensively for film and radio broadcasts and after Paul Hindemith’s endorsement, became the instrument of choice for ‘serious’ electronic music composition (Hindemith’s switching of allegiances from Jörg Mager’s Sphärophon family of instruments to the Trautonium signalled the end  of Mager’s career in instrument design). A portable version, the ‘Konzerttrautonium’ was designed in 1936 specifically for the composer  Harald Genzmer’s ” Conzert für Trautonium und Orchestrer” and saw more than fifty performances before the outbreak of the war.

Berlin had in the early Thirties become the world capital of electronic music, with inventors and designers such as Jörg Mager , Oskar Vierling , Fritz Sennheiser , Bruno Helberger, Harald Bode, Friedrich Trautwein and Oskar Sala (with much of the work centred around the Heinrich-Hertz-Institute). These instruments often explored radical new approaches to tonality and expression and were enthusiastically adopted by the avant-garde of the period. This period of musical ferment coincided with the seizure of power by Adolf Hitler’s National Socialist party (NDSAP), who initially tried to absorb this strain of modernism for their own propaganda ends – indeed, the name ‘Volkstrautonium’ echoes the name ‘Volkswagen’ as a peoples instrument for a modern, new Germany. On the 18th August 1933, Joseph Goebbels (Hitler’s Propaganda Minister) presided over the IFA ‘Internationale Funkausstellung’ (International Radio Exhibition) in Berlin. The music for the exhibition was provided by the ‘Future Orchestra’ (Das Orchester der Zukunft) composed of the most advanced electronic instruments of the time: The Volkstrautonium played by Oskar Sala, Bruno Helberger’s Hellertion, Oskar Vierling’s Elektrochord , the Neo-Bechstein of Walther Nernst, a collection of electric violins and cellos and Leon Termen’s  Theremin.

The rise of the Hitler’s National Socialist party presented electronic and avant-garde musicians with a difficult choice; either the hope that by collaborating they would survive and be left alone and be able to continue working or, simply, leave the country. Trautwein, who had joined the NDSAP in the late thirties used his connections:

Luckily Trautwein knew a general who was on our side and arranged that we could play the instrument to the minister of propaganda Joseph Goebels, Hitler’s right hand man. I Played something by Paganini and of course he liked it. After that, they left us in peace.
Oskar Sala

This collaboration resulted in a commission from the Reich’s Radio organisation for several new instruments to be built for a weekly fifteen minute programme “Musik Auf Dem Trautonium” (playing German classical music accompanied by a pianist) and later commissions to use the instrument at large scale NDSAP rallies, outdoor concerts, speeches and, (alongside other electronic instruments such as Vierling’s GrosstonOrgel) the Olympic Games in Berlin in 1936. However, this patronage was short-lived as the Nazi’s asserted their traditional conservatism; Atonal, Experimental and avant-garde music alongside Jazz and other non-German culture was branded ‘entarte’ or ‘degenerate’. Trautwein and Sala’s workshop was denied funding and closed, the Trautonoium was relegated to performing Reich-approved music. Sala spent the war years touring throughout Germany and Axis occupied countries until he was conscripted in 1944 and sent to the Eastern Front

The Warbo Formant Orgel

Harald Bode’s first commercial design was the wonderfully named ” Warbo Formant Orgel” built while at the Heinrich-Hertz Institut für Schwingungsforschung at the Technische Hochschule in Berlin. The Warbo Formant Orgel was designed and built with the musical input from the composer and band-leader Christian Warnke (hence ‘War- Bo’  Warnke/Bode);

“Christian made the contribution of a musician — that means he told me what to do as far as all the features the instrument should have. I’ll have to go into more detail. Christian Warnke was a composer and musician, a bandleader with a fine ear for music, and he was an excellent violinist. He wasn’t involved in the design per se, just the specifications of the Warbo. And he sponsored the project on a minimum budget. Mind you this was in the second part of the 30s, which had still terrible after-effects of the depression. But the Warbo was my first major contribution in the field.”
Harald Bode in  SYNE magazine 1980

Two versions of the instrument were made and later stored at the  Heinrich-Hertz Institute in Berlin. The institute was completely destroyed during the war and with it the Warbo Formant Orgel. No recording of the Warbo Formant have been found. As with many other instruments designed by Bode the ‘Warbo Formant Orgel’ pioneered aspects of electronics that became standard in later instruments. The Warbo Formant Orgel was a partially polyphonic four-voice keyboard instrument with 2 filters and key assigned dynamic envelope wave shaping – features that were later used on the postwar ‘Melodium’ and  ‘Melochord’.

“… It [The Warbo Formant Orgel] was built with a relaxation type of oscillator. Four oscillators actually, that were selected for the 44-note keyboard. The major problem being the stability of the oscillators, which is critical when comparing one with the other, especially with four. So I dropped the idea of a four-note organ at that time and went on to the Melodium, which was created in 1938 and used in many large performances with the Berlin Philharmonic as a solo instrument. It was also used in some significant motion pictures of that era.”

Biographical notes

Harald Bode; October 19, 1909 Hamburg Germany – January 15, 1987 New York USA.

Harald Bode; October 19, 1909 Hamburg Germany – January 15, 1987 New York USA.

Bode Studied  mathematics, physics and natural philosophy at Hamburg University, graduating in 1934. In 1937, with funding support provided by the composer and band-leader, Christian Warnke, Bode produced his first instrument the ‘Warbo-Formant Orgel’ (‘Warbo’ being a combination of the names Warnke and Bode). Bode moved to Berlin in 1938 to complete a postgraduate course at the Heinrich Hertz Institute where he collaborated with Oskar Vierling and Fekko von Ompteda. During this period Bode developed the ‘Melodium’ ;  a unique monophonic touch-sensitive, multi-timbral instrument used extensively in film scores of the period.

When WWII started in 1939 Bode worked on military submarine sound and wireless communication projects “…We had the only choice in Germany, to go to military service or do work for the government. I praise myself lucky, that I was able to go to the electronic industry” and moved to the  small village Neubeuern in southern Germany, where in 1947 Bode built the first European post-war electronic instrument, the ‘Melochord’. In 1949 Bode joined the AWB company where he created the  ‘Polychord’ a simpler, polyphonic version of the ‘Melochord’ which was followed by the ‘Polychord III’ in 1951 and the  ‘Bode Organ’, a commercial organ which became the prototype for the famous Estey Electronic Organ. After leaving AWB, Bode’s designs included the ‘Tuttivox’, a miniature electronic organ and collaborated on a version of Georges Jenny’s ‘Clavioline’, both big sellers throughout Europe.

In 1954 Bode moved to the USA, settling in Brattleboro, Vermont where he lead the development team (and later, Vice President)  at the Estey Organ Corporation. In 1958, while still working at Estey, Bode set up the Bode Electronics Company where in March 1960 he created another unique instrument; a modular synthesiser “A New Tool for the Exploration of Unknown Electronic Music Instrument Performances” known as the  ‘Audio System Synthesiser’ which Robert Moog used as the basis for his line of new Moog synthesisers.

After the Estey Organ Company foundered in 1960, Bode joined the Wurlitzer Organ Co and moved to Buffalo, New York where he was one of the first engineers to recognise the significance of transistor based technology in electronic music.  Bode’s concepts of modular and miniature self-contained transistor based machines was taken up and developed in the early 1960′s by Robert Moog and Donald Buchla amongst others. 1962 saw the beginning of a long collaboration between Bode and the composer Vladimir Ussachevski at the  Columbia Princeton Center for Electronic Music which lead to the development of innovative studio equipment designs such as the  ‘Bode Ring Modulator’ and ‘Bode Frequency Shifter’. The commercial versions of these inventions were produced  under the Bode Sound Co and under license Moog Synthesisers.

Harald Bode retired in 1974 but continued to pursue his own research. In 1977 he created the ‘Bode Vocoder’ (licensed as the ‘Moog Vocoder’). In 1981 he developed his last instrument, the ‘Bode Barberpole Phaser’.

The ‘Trautonium’ Dr Freidrich Trautwein. Germany, 1930

Dr Freidrich Adolf Trautwein (b Würzburg 1888, Germany; d Düsseldorf 1956)

The Trautonium was an important electronic musical instrument developed by the electrical engineer Freidrich Trautwein in Germany in 1930. Trautwein designed the first version of the instrument with the aim of freeing the performer from the restrictions of fixed (Piano) intonation. To achieve this, he removed the usual piano-style manual in his design and replaced it with a fingerboard consisting of a metal wire stretched over a rail, marked with a chromatic scale. By pressing the wire, the performer touches the rail below and completes a circuit generating a tone. A similar technique, copied by the Trautwein, was a feature of Bruno Hellberger’s Hellertion in 1929 and some time later in the Ondes Martenot.

The position of the player’s finger on the wire determines the resistance in the wire which in turn controls the pitch of the oscillator. This unusual approach allowed a great deal of expressive flexibility; by pressing harder on the wire, the player could subtly change the volume, and by moving the finger from side to side the instrument could produce violin like glissandi or more subtle vibrato effects. Overall volume was controlled by a foot-pedal allowing the performer to vary the volume and envelope of the notes.

Early version of the Trautonium

An early 1930′s version of the Trautonium at the Deutsches Museum, Berlin

The first Trautonium was a fairly simple monophonic vacuum tube ‘synthesiser’  generating sound from a single thyratron RK1 tube oscillator. However, by passing this tone through a series of resonant filters this simple sawtooth waveform could be coloured with a wide range of timbre characteristics. This unique form of subtractive synthesis (i.e. filtering down an existing complex waveform rather than creating a complex waveform from combinations of simple sine waves) produced a tone that was distinctive and unusual when compared to the rather plain sound of other valve instruments in the 1920-30′s.

The commercial version of the Trautonium or ‘Volkstrautonium’ was manufactured and marketed by Telefunken in 1932. But, probably due to the unpopularity of a new, somewhat complicated keyboard-less instrument and high purchase price (c400 Reichs Marks;  equivalent of two and a half months of a worker’s salary  or more than five times the price of radio), only around thirteen items were sold and by 1938 it was discontinued. Despite the lack of domestic commercial interest, a number of composers wrote works for the instrument including Paul Hindemith ( who, switching allegiances from Jörg Mager’s Sphäraphon, learnt to play the Trautonium)  ‘Concertina for Trautonium and Orchestra’ , Höffer, Genzmer, Julius Weismann and most notably Oskar Sala. Sala became a virtuoso on the machine and eventually took over the development of the Trautonium producing his own variations- the ‘Mixtur-Trautonium’, The ‘Concert-Trautonium’ and the ‘Radio – Trautonium’. After the commercial failure of the instrument Trautwein abandoned further development to Oskar Sala who continued to work with the Trautonium until his death in 2002. Trautwein also produced an ‘Amplified Harpsichord’ in 1936 and ‘Electronic Bells’ in 1947.

Trautwein studied electrical engineering at the Technical University of Karlsruhe and later, law in Berlin. In the First World War he was a lieutenant in the German Army and led a mounted radio squad. After the war in 1919 he studied Physics in Heidelberg and Karlsruhe where he received his PhD in engineering. The following year he started working for the State Telegraph Service where he was involved in the establishment of the first German radio station in Berlin.

In 1929 he took a teaching position at the Berlin State Music Academy where he started early development of the Trautonium with the patronage and guidance of the composer Paul Hindemith. The first version of the Trautonium was completed in 1930 and a commercial version produced in 1933 by Telefunken; the Telefunken Volkstrautonium model Ela T42. After the commercial failure of his invention, Trautwein abandoned the instrument to composer and Trautonium virtuoso, Oskar Sala

The Trautonium played by Oskar Sala, incorporated into the 'Das Orchester der Zukunft (The Future Orchestra), alongside a Hellertion, Thereminvox and Elektrochord.

In 1949 Trautwein worked in briefly at the Bikla School for Photography and Film in Düsseldorf and then established the sound engineering course at the Düsseldorf Conservatory (now the Robert-Schumann-Hochschule in Dusseldorf ) which still forms the basis of the current sound engineering training unit. In 1952 Trautwein developed an evolved version of the Trautonium for WDR Electronic Music Studio, the Electronic Monochord. Trautwein died in Düsseldorf in 1956.

The ‘Saraga-Generator’ Wolja Saraga, Germany ,1931

The Saraga-Generator was developed by the electrical engineer and physicist Wolja Saraga at the Heinrich-Hertz Institut Für Schwingungsforschung in Berlin, Germany around 1931. The Saraga Generator was an unusual theatrical photo-electrical  vacuum tube instrument. The Saraga Generator was designed to be used for theatrical production where the sound would be triggered by movement in front of the instrument. The instrument consisted of a photoelectric cell mounted on the white painted inside surface of a box with a small slit cut on one face. A low voltage neon lamp was placed at some distance from the box on a stage and the performers movements interrupting the light beam caused variations in pitch. Envelope and timbre were affected by manipulating a hand held switch device, the overall volume being controlled by a foot pedal. The instrument had a tonal range of four octaves.
