Does music affect animals?
I did my dissertation on the effects of music on chimpanzees. It was an observational study and I played classical music into the habitats of captive chimpanzees at varying intervals and observed behaviours for a month. The study demonstrated a decrease in aggressive behaviours while the music was on, and an increase in rest/sleep periouds. Whether this was a direct result of the music, or of the influence the music had in minimalising the impact of the noise from the zoo visitors was unclear however. Personally though I think that they did certainly enjoy having the music on and they seemed very responsive to it.
