-< FM radio brings you " tural color" music It's just the difference between a photograph and a man's best girl, in person I Scientists will tell you that every note of music you hear is com posed of a "fundamental" tone, and a series of "overtones." For technical reasons, which needn't concern us here, conven tional radio cannot reproduce all the overtones of a given musical instrument. As a result, something is lacking-some of the depth and purity of tone has been lost. But a new kind of radio, known as FM, reproduces tones and over tones as they have never been reproduced before . . . brings you "natural color" music without static or interference of any kind! The General Electric FM (Fre quency Modulation) Radio is an electronic instrument, developed by G-E engineers with Major E. H. Armstrong, originator of FM.
