Scientific article demonstrating that certain musical styles and tempi, notably slow guzheng (Chinese zither) music, reduce stress and cortisol levels in aquarium fish. Music can produce positive or negative behavior, depending on the species and the tempo. Slow guzheng music was found to be the most soothing of the styles in the experiment, especially for guppies.
