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.

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.

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

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

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’ was developed by the electrical engineer and physicist Wolja Saraga at the Heinrich-Hertz Institut Für Schwingungsforschung (HHI) in Berlin, Germany around 1931. The Saraga Generator was an unusual photo-electrical vacuum tube instrument originally designed to be used for theatrical production where the sound would be triggered by movement in front of the instrument.

The original instrument consisted of a single photoelectric cell mounted on the white painted inside surface of a box with a small ‘V’ shaped 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 causing variations in pitch in a tone generated using the well established  heterodyning effect of two vacuum tubes. Later versions were designed to be played in a way similar to the Theremin with one hand held in the air controlling the pitch by interrupting the light beam –Envelope and timbre were controlled by manipulating a hand held switching device, the overall volume being driven by a foot pedal. The Saraga Generator was monophonic with a tonal range of four octaves.

The Saraga Generator was patented in 1932 and demonstrated at the Berlin Radio Exhibition (IFA Berlin) in the same year.

Saraga took a version of the Generator to London after he left Berlin for the UK in 1938 ( He also brought a Volkstrautonium purchased as a promotional model from Telefunken) . He gave several presentations of the instrument for the Institute of Musical Instrument Technology (Holloway Rd, London N7) in May 1945 entitled “A Homophonic or single-note electronic musical instrument with a photo electric cell as playing manual – demonstration of an experimental model” and searched for commercial applications for the instrument including film soundtrack music and musical therapy for blinded war veterans.

Difficulties in sourcing electronic components in post-war Britain hampered development of the instrument which was eventually overtaken by more sophisticated and versatile electronic instruments of the 1950s

Wolja Saraga: Biographical Notes

Saraga was a German Jewish Physicist, born in Berlin to a Romanian father and a Russian mother. Saraga studied telecommunications at the Heinrich Hertz Institute (‘Heinrich-Hertz Institut Für Schwingungsforschung’ or ‘HHI’) at the Technical University, Berlin under Prof Gustav Leithäuser – alongside luminaries such as Oskar VierlingHarald Bode , Winston Kock and Friedrich Trautwein.

It was during his time at the HHI that he began investigations into electronic musical instruments, his published papers detailing; a dual oscillator Aetherophone or ‘Theremin‘ , a ‘Poly-rhythmic Electronic Musical Instrument’ , The workings of the Volkstrautonium and his design for a photo-optical instrument, the ‘Saraga Generator’ first built in 1931. Saraga became a research assistant at the institute and later  a lecturer from1929-1933. He also studied physics and mathematics at the Humboldt University of Berlin , where he was awarded a Dr. phil. in physics in 1935.

During his time in Berlin, Saraga was very energetic in promoting the potential of electronic music; He made several public presentations and demonstrations of electronic instruments including Theremins, Trautoniums and his own ‘Saraga Generator’. Saraga was also present playing the ‘Saraga Generator’ at the 1932/3 International Funkaustellung (IFA) where the first ever electronic musical orchestra performed (Das ‘Orchester der Zukunft’).

"Electric Concerts" with the electroacoustic "orchestra of the future", 1932/1933 On the occasion of the 9th and 10th IFA in Berlin 1932 and 1933 for the first time found concerts with "Electric Music" instead. They played by the so-called "Orchestra of the future" all electroacoustic musical instruments then available. The "Elektischen concerts" made at the time an exceptional level of interest and broad support in the public, as the cooperating with private Theremingerät Erich Zitzmann-Zerini [second right] the engineer Gerhard Steinke told while gave him this original image. The orchestra consisted of two theremin instruments Trautonium [by Trautwein], Heller desk [of B. and P. Helberger Lertes], a neo-Bechstein grand piano [for suggestions of O. Vierling, S. Franco, W. Nernst and H . Driescher], Vierling piano [electro Acoustic piano by O. Vierling], electric violin, electric cello and Saraga generator [a light-electric device by W. Saraga, in principle, similar to the Theremingerät]. Photo: archive Gerhard Steinke

It became clear to Saraga in 1935-6 that as a Jewish scientist he would have no future in the new National Socialist German Reich and began to apply to leave the country, first of all to Switzerland and then to the UK. Saraga finally left Berlin in 1938 at the age of 29. he was initially held for six months on the Isle Of Man Hutchinson Camp as a German internee but was given a position working for the ‘Telephone Manufacturing Company’ (or ‘TMC’) in St Mary’s Cray, Kent where, despite his unhappiness at his employers lack of interest in research, he remained until 1958.

Saraga then joined The Associated Electrical Industries Research Laboratory in Blackheath, London as a Research Scientist and Group Leader where he specialised in telephony filter design. In 1962, Saraga’s key contributions were recognised by the award of the Fellowship of the Institute of Electrical and Electronics Engineers, ‘for contributions to network theory and its application in communications’. In 1972, Saraga moved full time to Imperial College, London where he became a postgraduate lecturer and researcher in network theory and mathematics.

Saraga wrote a number of books and filed several patents on network theory and telephony.

The Monochord was commissioned from Dr Freidrich Trautwein, the inventor of the Trautonium, by the Electronic Music studio of North West German Radio studios, Köln to upgrade its synthesis module which consisted at the time of one sine wave generator and filter system. The Monochord was basically a modified concert Trautonium with a monophonic variable pitch interval keyboard controlling a valve based tone generator. The keyboard was pressure sensitive and allowed one hand to play pitched notes while the other changed timbre and variations of the envelope shape. A foot pedal controlled the overall volume output from the machine.
