Plants have been shown to significantly increase their rate of growth when stimulated by specific sound frequencies. In the 1950's, Indian botanist T.C. Singh observed under a microscope the protoplasm streaming in an Asian aquatic plant, which normally increases at sunrise, and discovered that such streaming could be induced at other times of the day by activating an electrically driven tuning fork. He then experimented with recorded South Indian violin music played to a wide variety of plants, with frequencies of the fundamental tones in the 100 to 600 Hz range; significantly increased growth rates resulted. [7] About the same time, a Canadian named Eugene Canby began subjecting test plots of wheat to recordings of violin sonatas by J.S. Bach, and found that yields increased by 66%. Other tests in Russia, the U.S., and Canada with ultrasonic frequencies yielded similar increases in the growth rates of other plant species.
Various researchers then determined that the range of frequencies around 5000 Hz were especially potent in stimulating plant growth. During the 1960's, researcher Dorothy Retallack determined that these frequencies were best administered in the form of classical music (compositions of J.S. Bach, Haydn, Beethoven, Brahms, Schubert, and other European 18th and 19th century composers; traditional North Indian music performed on sitar and tabla), played intermittently for several hours per day. [8a, 8b] A Minnesota plant breeder named Dan Carlson collaborated with a music teacher named Michael Holtz to create an audio tape with a combination of frequencies centered about the 5000 Hz range, which Holtz immediately recognized as being very similar to the sound of a bird chorus at dawn. Carlson then used this music to induce record-breaking growth rates in Purple Passion vine plants. [7]
Retallack also experimented with various types of rock music to see what effects they would have on plant growth. Plants "listening" to selections from Led Zeppelin, Vanilla Fudge, and Jimi Hendrix became stunted or gangly, with long stems and sparse leaf growth, some bending away from the sound source; after 16 days, most of these plants died.
Retallack also found that the discordant music of 20th century composers Arnold Schönberg and Anton von Webern also caused plants to atrophy, but not to the degree of the rock music. Schönberg is considered to be the father of 12-tone music, characterized by a total "freedom" from harmonic contraints, wherein all 12 tones of the western musical scale are ideally considered to be of equal weight and value. Twelve-tone principles of composition were eagerly embraced by avant garde faculty at music schools during the early 20th century, and over the following decades began to appear in popular music, and in background music for television and radio programs. The 12-tone style is what gives music for horror and suspense films its particular capacity to shock and terrorize.
