New Phonograph Record Plays Half Hour Music Program (Feb, 1932)

New Phonograph Record Plays Half Hour Music Program

THE phonograph, long overshadowed by the radio, now promises to come back into popularity, thanks to the development of an improved type of phonograph record recently introduced. Capable of running for a full half hour, the new long-playing record reproduces entire symphonies and vaudeville and musical comedy acts with-out the necessity of changing the discs.

The long-playing feature is obtained by slowing down the turn-table speed 78 to 33 -1/ rpm., and by introducing almost double the number of grooves in the playing surface. The new discs are made from a composition called Vitrolac, which permits placing finer grooves in the record.

The slower turn-table speed for playing the new records is obtained by the use of a special gear shift arrangement, which can be installed in any electric phonograph. The needles are chromium plated.



Will canned music inspire future warriors? Veteran army bandmasters in Denmark were taken aback when a lumbering sound truck recently took the place of a regular band and led a detachment of Danish soldiers on a cross-country march. Martial airs played upon a phonograph were amplified and projected to front and rear by horns atop the truck. Lively discussion was stirred up two years ago in this country when the United States Army became interested in mechanical bands to replace musicians. A sound truck for this purpose was designed, built, and offered for test by the Radio Corporation of America (P.S.M., Aug., ’30, p. 48). Its volume equalled that of two Army bands and the quality of music was called as good as the average in the service. To date, however, no definite move to adopt the mechanical substitute for bandsmen has been made public.

How Music Heals the Sick (Oct, 1937)

How Music Heals the Sick


By E. W. Murtfeldt

BEETHOVEN’S Moonlight Sonata—three times a day. That is how doctors’ prescriptions may read in the near future, according to reports from the world’s leading medical centers. For in laboratories, hospitals, prisons, and mental clinics, research experts are uncovering strange facts that throw new light on the weird effects of music on our physical and mental health.

Just recently, for instance, Prof. S. V.Kravkov, a Russian scientist, discovered that music and similar sounds can even improve a listener’s eyesight as much as twenty-five percent. As little as the rhythmic ticking of a clock, experiments showed, served to stimulate the vision. A practical application of the discovery, the Soviet professor points out, is expected to serve as an aid to astronomers, microscopists, engravers, and others whose work depends on the strength and accuracy of the eyes. Even more astonishing, however, are tests being carried on in this country. Not long ago, Moissaye Boguslawski, famous pianist, conducted a series of novel experiments in a Chicago hospital for the insane. Seated before an Italian mother so mentally deranged that she refused to look at her young baby and demanded that she be treated like an animal, Boguslawski played a group of Italian melodies ranging from nursery tunes to folk songs. The woman showed no reaction until he began an aria from the opera “II Trovatore.” Before he had finished, the patient began to weep and begged attendants to bring her baby to her.

The first four notes of Beethoven’s Fifth. (Oct, 1982)

The first four notes of Beethoven’s Fifth.
Musical notes like these never existed before 3M invented the Digital Mastering System.

It uses computer technology to record every nuance of a piece of music in binary numbers. So that when reproduced, every note can be heard with such uncanny crispness and clarity, you can hear music the way Beethoven wanted it to be heard.

At 3M, by listening to people’s needs, we’ve pioneered over 400 products to serve the needs of the communication arts field. We’ve developed everything from videocassettes to lithographers tape to photo offset plates.

All because at 3M, we’re in the business of hearing. So let us hear from you.

3M hears you…

The “Telecolor” Translates Music Into Light (Nov, 1931)

Music visualizations that beat WinAmp by about 70 years.

The “Telecolor” Translates Music Into Light

COLOR has long been a favorite word to describe the quality and the mood of music; perhaps because some individuals inevitably associate a certain chord with a certain color. This is doubtless only an individual peculiarity; because all people do not match the same music with the same colors. However, a scientific means has been found to turn music into light; and thus make a radio program appeal to the eye (even without television), as well as the ear. The new invention, the “tele-color” shown here, differs from earlier color organs, such as the “clavilux,” in being automatic in its actions.

Reducing Reduced to a Science

ARE you bulky of body, and heavy of heart? Would you really like to reduce? Will you accept without cost the proof that you can? Then read what this man has done! Not long: ago, in Chicago, it was stated that the scientific secret of weight regulation had been discovered. Wallace, a leading physical director, had worked seventeen years to make the announcement. But it did not take long to prove it was true.

New Electric Reproducer Plays Piano Accompaniment (Feb, 1932)

New Electric Reproducer Plays Piano Accompaniment
ONE of the strangest contraptions yet to make its appearance in the musical world was exhibited recently at the German Radio Show in Berlin. Known as the “Helertion,” the device performs the function of playing an accompaniment to a grand piano. The notes are picked up by a microphone and are altered by changing the resistance in the lattice circle, which reproduces spheric sounds and noises together with the ordinary tones of the piano.

The alteration tone is carried on through a series of amplifiers and reproduced through a battery of loud speakers. Auditors who have given the system a try-out declare that the scheme opens up a new field for musical reproduction from an ordinary . grand piano. The tonal range is as great with the reproducer as with the piano itself.

Dashboard Keyboard Operates Car-Exhaust Calliope (Nov, 1940)

Dashboard Keyboard Operates Car-Exhaust Calliope
Under the hood of the automobile owned by Leo Feuchter, of Ironton, Ohio, is a homemade calliope which is powered by the exhaust of the engine and played by means of an organ-type keyboard at the right side of the dashboard. Depending upon the speed at which the motor is running, the sound of the calliope can be heard from six to eight blocks away. To start the music, the operator presses a pedal, diverting the exhaust gases into the instrument. The range of the calliope is two octaves. Feuchter, a sixty-five-year-old automobile mechanic, designed and constructed the unique installation, which has attracted wide attention in parades and at conventions.
