某位學者操控某項變因，於完全相同的環境下，種植著相同的植物。該項控制變因是，使各個植物分別持續聽著不同的音樂。其中一盆聽的是充斥著負面俚語的重金屬搖滾，另一盆聽的是莫查特的音樂，還有一盆則是持續聆聽北印度的古典音樂。
幾週後，該植物們在成長的過程上，出現了明顯的差異性。聽莫查特的植物，長得既健康又充滿生命力；聽重金屬的植物，則瀕臨死亡、極盡枯萎；而聽北印度古典音樂的植物，在盆中茂盛、洋溢的開展著。
這是我在接觸印度音樂之前，高中時從某位老師那聽來的。雖然無法判定實驗的真偽，但後來又陸續從許多人那得知相同的訊息，應該可說是個有名的實驗吧。
發現了!! 稍微不同。

The Plant Experiments
In 1973, a woman named Dorothy Retallack published a small book called The Sound of Music and Plants. Her book detailed experiments that she had been conducting at the Colorado Woman’s College in Denver using the school’s three Biotronic Control Chambers. Mrs. Retallack placed plants in each chamber and speakers through which she played sounds and particular styles of music. She watched the plants and recorded their progress daily. She was astounded at what she discovered.
Her first experiment was to simply play a constant tone. In the first of the three chambers, she played a steady tone continuously for eight hours. In the second, she played the tone for three hours intermittently, and in the third chamber, she played no tone at all. The plants in the first chamber, with the constant tone, died within fourteen days. The plants in the second chamber grew abundantly and were extremely healthy, even more so than the plants in the third chamber. This was a very interesting outcome, very similar to the results that were obtained from experiments performed by the Muzak Corporation in the early 1940s to determine the effect of "background music" on factory workers. When music was played continuously, the workers were more fatigued and less productive, when played for several hours only, several times a day, the workers were more productive, and more alert and attentive than when no music was played.
For her next experiment, Mrs. Retallack used two chambers (and fresh plants). She placed radios in each chamber. In one chamber, the radio was tuned to a local rock station, and in the other the radio played a station that featured soothing "middle-of-the-road" music. Only three hours of music was played in each chamber. On the fifth day, she began noticing drastic changes. In the chamber with the soothing music, the plants were growing healthily and their stems were starting to bend towards the radio! In the rock chamber, half the plants had small leaves and had grown gangly, while the others were stunted. After two weeks, the plants in the soothing-music chamber were uniform in size, lush and green, and were leaning between 15 and 20 degrees toward the radio. The plants in the rock chamber had grown extremely tall and were drooping, the blooms had faded and the stems were bending away from the radio. On the sixteenth day, all but a few plants in the rock chamber were in the last stages of dying. In the other chamber, the plants were alive, beautiful, and growing abundantly.
Mrs. Retallack’s next experiment was to create a tape of rock music by Jimi Hendrix, Vanilla Fudge, and Led Zeppelin. Again, the plants turned away from the music. Thinking maybe it was the percussion in the rock music that was causing the plants to lean away from the speakers, she performed an experiment playing a song that was performed on steel drums. The plants in this experiment leaned just slightly away from the speaker; however not as extremely as did the plants in the rock chambers. When she performed the experiment again, this time with the same song played by strings, the plants bent towards the speaker.
Next Mrs. Retallack tried another experiment again using the three chambers. In one chamber she played North Indian classical music performed by sitar and tabla, in another she played Bach organ music, and in the third, no music was played. The plants "liked" the North Indian classical music the best. In both the Bach and sitar chambers, the plants leaned toward the speakers, but he plants in the Indian music chamber leaned toward the speakers the most.
She went on to experiment with other types of music. The plants showed no reaction at all to country and western music, similarly to those in silent chambers. However, the plants "liked" the jazz that she played them. She tried an experiment using rock in one chamber, and "modern" (dischordant) classical music of negative composers Arnold Schönberg and Anton Webern in another. The plants in the rock chamber leaned 30 to 70 degrees away from the speakers and the plants in the modern classical chamber leaned 10 to 15 degrees away.
I spoke with Mrs. Retallack about her experiments a few years after her book was published, and at that time I began performing my own experiments with plants using a wood-frame and clear-plastic-covered structure that I had built in my back yard. For one month, I played three-hours-a-day of music from Arnold Schönberg’s negative opera Moses and Aaron, and for another month I played three-hours-a-day of the positive music of Palestrina. The effects were clear. The plants subjected to Schönberg died. The plants that listened to Palestrina flourished.
In these experiments, albeit basic and not fully scientific, we have the genesis of a theory of positive and negative music. What is it that causes the plants to thrive or die, to grow bending toward a source of sound or away from it?
