In experiments done in the 1960s and 1970s, plants responded best to classical and Indian devotional music. In a controlled environment, plants exposed to these kinds of music had lush and abundant growth and good root development. Exposure to country music or silence brought about no abnormal growth reaction, while jazz produced more abundant growth. With rock music, plants did poorly. Their roots were scrawny and sparse and they seemed to be in a dying stage. Plants exposed solely to white noise died quickly.
