The Jowiphon. Hans Joachim Winckelmann. Germany 1935

One of several optical synthesis devices that emerged in Germany during the 1920’s and 30’s, the ‘Jowiphon’ was a simple monophonic radio-tube based instruments that was operated by playing a hand held light beam across a selenium photocall that in turn triggered an audible voltage pulse generated by a vacuum tube. The Jowiphon was very similar to a design of Wolja Saraga developed at the Heinrich-Hertz-Institut für Schwingungsforschung, Berlin around 1930.

“How amazed, however, was when I was recently with a radioing-meur who was my friend, and he showed me something similar, which at first seemed almost more startling than that Theremin device. He led me into a darkened room with a flashlight in the air – and lo and behold, from a loudspeaker set up somewhere, a music sounded very similar to that of the Theremin apparatus. Here, too, it was only a miracle until Mirmein’s friend explained the technical process.

By exposing a photocell to the flashlamp, an electric current is generated; this is converted into sound vibrations by a certain method, but another, as in the case of the Theremin appliance. The more the flashlight approaches the photocell, the greater the exposure, the electric current becomes stronger and the tones become higher. It all sounds very simple, but it requires a shaken-up amount of knowledge to weld these theoretically remote things into something practical and practical. The inventor has christened his “Jowiphon” sound, which is said to be similar to the Theremin device, but tends toward the string instruments like the violin or cello. But you can also easily create the deepest bass tones like the highest notes of a piccolo. As with the Theremin instrument the tone color and the volume can be changed arbitrarily.

Playing on these devices is no harder to learn than that of other instruments. Their only drawback may be that producing faster results makes some more trouble. As the inventor explained, the Jowiphon, which, like most musical instruments, is unanimous, can also be made into a polyphonic instrument like the organ. The fact that these instruments have not become so popular is largely due to the fact that in Germany two other electric musical instruments have been constructed to a very high degree of perfection, the Vierling Electrochord and the Trautonium.

The Vierling Electrochord is played like a grand piano and allows you to tune to six different tones. The Trautonium is a unanimous instrument that is played by pressing a metal string down on a metal rail. In this instrument, the change of timbre is up to the highest perfection. You can just as well create the sounds of a bass as a clarinet or piccolo. With four instruments you could play a complete string quartet. But it can also produce quite new sounds of surprising effect. The fantastic magic that I felt when I heard the first ether wave music was gone. But I do not feel poorer about it. Despite all knowledge of the technical processes, there is always a remnant of the mystery that one feels again and again when one hears these instruments, which has given us the restraining technique of our century.

The Magneton, designed by Wilhelm Lenk at the University of Vienna, was a tone-wheel organ-like electronic instrument based on the same principles as Cahill’s Telharmonium (c1900)  and the later Hammond Organ of Laurens Hammond and  John Hanert; the electromagnetic principle of producing a voltage tone and associated timbres by spinning varied shaped metallic wheels within a magnetic field.

The instrument’s contribution to tonewheel technology was to achieve a constant fixed rotation by using a frequency controlled motor regulator. This allowed the player to easily and accurately transpose the instruments switch at the flick of a switch.

The first promotional model of the instrument was produced by the Vienna piano company Stelzhammer in 1930 – four years before the first Hammond organ hit the market. The instrument was designed as a practice instrument for ‘real’ pipe organs and as a way of encouraging active participation from the congregation in sacred music (as espoused by the “Popular Liturgy Movement” in pre-war Austria).

“The slavish imitation of the sound of an organ and its characteristic rigidity was deliberately avoided, thereby giving the tone character of the instrument a number of special characteristics. What I like particularly in the magneton, 8 although I grew up with the pipe organ and have been inseparably associated with it for 50 years, is the fact that this new instrument is not an enemy of the historic organ.”

Vinzenz Gollerin the ‘Zeitschrift fur Instrumentenbau’ Vol. 54, 1933/34, p. 103

Despite a promising start, the Magneton failed commercially – only a few production models were built. A single surviving model can be found at the Vienna Museum of Technology, Austria.

Rudolf Stelzhammer. Biographical notes.

Rudolf Stelzhammer was born into a Viennese family of piano makers on the  03.11.1893. After learning the craft of piano construction and working in the family business he travelled throughout Europe and America working for large instrument manufacturers. Returning to Austria in 1924 he founded his own company in Vienna and from 1935 became the ‘guild master’ of the Austrian musical instrument producers. In 1966 Stelzhammer sold the business to the Ehrbar piano Company in Vienna. Stelzhammer was known for his scientific and electro-acoustic research which lead to several improvements in piano design. Stelzhammer was involved in the development of photoelectric experiments and was involved in the creation of the ‘Selenephon’ (1922) a device for printing optically recorded audio onto movie film. Rudolf Stelzhammer died in Vienna, Austria on 01.16.1967

Frederick Sammis invented the “singing Keyboard” in 1936, a precursor of modern samplers, the instrument played electro-optical recordings of audio waves stored on strips of 35mm film.

Let us suppose that we are to use this machine as a special-purpose instrument for making “talkie” cartoons. At once it will be evident that we have a machine with which the composer may try out various combinations of words and music and learn at once just how they will sound in the finished work. The instrument will probably have ten or more sound tracks recorded side by side on a strip of film and featuring such words as “quack” for a duck, “meow” for a cat, “moo” for a cow. . . . It could as well be the bark of a dog or the hum of a human voice at the proper pitch.

(Frederick Sammis, quoted in Rhea [1977]

Sammis had moved to Hollywood in 1929 to lead RCA into the era of film sound. Sammis was already familiar with the Moviola, a sound- and filmediting table that incorporated photoelectric cells. Using methods that were being developed for the new ‘talkies’, he recorded sung and spoken words onto individual strips of film. He then attached the resulting strips to the keyboard in such a way that a specific strip would be drawn across the optical cell when he depressed a corresponding key.  More recent instruments such as the Mellotron and Chamberlin use a similar technology of triggered and pitched magnetic tape recordings.

Dr Phillip Thomas a research physicist at the Westinghouse Research laboratory created the ‘Marimbalite’ sometime around 1935 as a way of publicising Westinghouse’s research into photo-electric technology. Other promotional applications included ‘Rastus’ the rubber negro robot who could be commanded to stand up and talk when illuminated by a torch beam.

The Marimbalite was an electro-mechanical device which created sounds mechanically from light triggered vibrating tubes, Dr Thomas was able to ‘play’ the Marimbalite with a torch in each had:

“Dozens of photo-cells and radio tubes are lined up side by side atop the new musical device. For each musical note there is an oscillating circuit which produces electrical vibrations when light is directed on that circuits photo-cell. Reproducers convert the electrical vibrations into sound which is directed into the marimba pipes.”

Dr Phillip Thomas worked at Westinghouse Research laboratory for thirty five years and developed numerous inventions including primitive robots, ‘vortex chimneys’, lightbulbs, voice activated switches, ultra-audible microphones. After retirement he proposed to study the possibility of recording telepathic human thoughts –there is no record of his findings with this endeavour.

In the early 1920s Thomas invented an “ultra-audible” microphone that enabled “scientists to hear sounds inaudible to the naked ear.” He would later work on radio signal-controlled electric circuitry, and a vortex gun designed to eliminate smoke from factories by shooting it in vortex rings high into the atmosphere. After World War II, Thomas believed that the answer to mental telepathy might be found in the unexplored frequency band between ultra-short radar waves and the longest waves of light.”

R.C.Hitchcock and the Westinghouse Organ 1931

The Westinghouse Organ was a semi-polyphonic multi vacuum tubed electronic organ designed by the research engineer Richard. C. Hitchcock for Westinghouse Electric Manufacturing Company, Pittsburgh, Pennsylvania USA. The organ was played on a three octave manual keyboard using a foot pedal for volume control. Hitchcock’s instrument allowed control of each note’s timbre by employing multiple vacuum tubes for each note to create adjustable natural harmonics of the fundamental note. The organ also had an electrical motor driven tremolo unit to shape the sound:

“…no previously known musical instruments. of the type to which my invention pertains, were provided with adequate means for tone and volume-control and, consequently, they were incapable of reproducing musical compositions with the same tone-color and nuances of expression that could be obtained with pipe-organs and pianos. In addition, the limitations of previously known electrical musical instruments were such as to preclude their proper tuning and they could not be satisfactorily utilized in orchestras wherein the other instruments were tuned to the tempered scale. It is, accordingly, an object of my invention to provide an electrical musical ‘instrument wherein each note of the scale shall be accompanied by the harmonic frequencies necessary to give it the requisite color.”

R.C.Hitchcock Patent Application 1930

The ‘Electric radio Organ’ was built to test the practicality of broadcasting electronic organ music over the radio rather than recording real pipe organs on-location with with the primitive microphones of the day (similar to the ‘Givelet Coupleaux’ Organ in France). The organ’s debut was at Pittsburgh’s KDKA radio station in 1930.

A New Instrument, Called a Radio Organ, is Demonstrated in Concert by Dr. Heinroth. United Press Staff Correspondent. PITTSBURGH, Jan. 23.

The squeals and squawks that are the bane of radio fans have been brought under control and combined in music rivalling that of the pipe organ. The new instrument, in fact, Is called a radio organ, and SO oscillating vacuum tubes replace the pipes. The first concert on the radio organ was played by Dr. Charles Heinroth, noted musician of Carnegie Institute, and though the event was not without a few impromptu notes, the half hour program amply demonstrated that the noise of radio tubes can be made beautiful. The radio organ is the product of the genius of R. C. Hitchcock of the Research Department, Westinghouse  The keyboard is like that of a regular three-octave organ and foot pedals to control the volume are provided.” The touch of a key plays the proper note ‘by causing one of the’ tubes to oscillate. The electric impulses thus set up may then he carried directly to a loud speaker which transforms them into sound. But they need not be transformed into sound at once, and this fact is held to open a vast realm of possibilities for the radio organ.. For instance, the music that is to say, the electrical impulses set up by the oscillating tubes may be broadcast without use of a microphone and not become audible until it is picked tip on the receiving sets. Likewise the possibility of a central organ with the music wired to several churches or theatres may -be easily be envisioned. Another advantage of the radio organ is that all the mechanism of the instrument may be placed in a basement room, with only the keyboard visible.

The Hardy-Goldthwaite organ was a type of early  analogue sampler, similar to the Welte Licht-Ton Orgel, The Superpiano and several other photo-electrical instruments of the period and was developed by the physicists Arthur Hardy and Sherwood Brown at the Massachusetts Institute of Technology at the request of DuVal R. Goldthwaite, chairman of the Interchemical Corporation (who apparently had originated the concept after working with Hardy on colour and ink chemistry). At the heart of the instrument was a single optical disc of photographed sound waves. The discs, created from translations of original instrumental sounds, rotate between a light a slit and a photo-electrical cell generating voltage outputs of various timbres. A small three octave manual keyboard operated a shutter within the instrument that projected a light beam through the specific tone on the disc correlating to the key’s pitch.

The instrument was said to be able to produce the timbres of an organ, trumpet, piano and strings – with the possibility of reproducing any sound that could be recorded to the glass disc.

Arthur C. Hardy born Worcester, Massachusetts:1895 died: 1977.

Arthur Hardy was a physicist best know for his work with spectrometers and colour analysers and was the author of the default text on the subject ‘The Principles of Optics’ . After the WWI Hardy worked at Kodak Research Labs and then transferred to Massachusetts Institute of Technology where he became chair of MIT’s physics department.

Hardy became president of the Optical Society of America from 1935-36 and in 1935 Hardy filed a patent for the first spectrophotometer – a device for measuring and recording colour values. It could detect two million different shades of colour and make a permanent record chart of the results. The patent was assigned to the General Electric Company of Schenectady, N.Y. which sold the first machine on 24 May 1935. It used a photo-electric device to receive light alternately from a sample and from a standard for comparison. 

After the outbreak of WWII Hardy founded the ‘Visibility Laboratory’ which focused on applying optics to such problems as camouflage, misdirection of aerial bombardment, target location, visibility of submerged objects at sea.

Since the 1920’s the Compton Organ Co had been the premier manufacturer of pipe organs for cinemas, churches and dance halls in the UK. In 1932 Compton developed their first electronic “pipe-less” organ the ‘Melotone’ intended as an add-on unit for conventional organs to extend their range. The Melotone’s sound was generated using the same tone-wheel technique as the Hammond Organ and the much earlier Telharmonium (1876), where a metal disc engraved with representations of sound waves spun within a magnetic field generating varying voltage tones. In this case two electrostatic tone wheels provided the sounds, amplified and fed to a large speaker horn in the organ loft. The Melotone was not intended as a complete instrument in itself and had it’s own ethereal synthetic character to contrast with a traditional pipe organ.

In 1938 Compton developed the Melotone concept into a stand-alone organ called the Electrone (or Theatrone) designed as a replacement for old pipe organs in churches and dance halls. This instrument had twelve tone generators and an organ-stop style range of voices. A post-war compact ‘economical’ version was brought out in 1952 also called the ‘Melotone’. Production of the organs continued until the 1960’s by which time tone-generator technology had become obsolete due to the arrival of cheaper and more dependable solid-state electronic circuitry.
