In 2002, a research study was done which studied the effects of five different types of audio stimulation on animal shelter dogs.. These five audio samples were human conversation, classical music, heavy metal music, pop music, and total silence. While heavy metal music caused the dogs to stand up and bark, the classical music cased them to rest more often.
Also, in 2000, an msnbc article reported that a harp player named Alianna Boone played her harp for hospitalized dogs in Florida and it was discovered that her soft pulls on the strings lowered heart and respiration rates in many cases.
