The effect of harp music on heart rate, mean blood pressure, respiratory rate, and body temperature in the African green monkey

Abstract

Background: The effectiveness of recorded harp music as a tool for relaxation for non-human primates is explored in this study. Methods: Konigsberg Instruments Model T27F-1B cardiovascular telemetry devices were implanted into nine African green monkeys (Chlorocebus aethiops). After post-surgical recovery, animals were exposed to recorded harp music. Telemetry data were collected on heart rate, mean blood pressure, respiratory rate, and body temperature for a 30-minute baseline period before music exposure; a 90-minute period of music exposure; and a 90-minute post-exposure period, where no music was played. Results: No statistical differences were noted in heart rate, mean blood pressure, respiratory rate, and body temperature between pre-exposure, exposure, and post-exposure periods. Conclusion: The lack of response in these African green monkeys may be attributable to their generally calm demeanor in captivity; experiments with a more excitable species such as the rhesus macaque might demonstrate a significant relaxation response to music. © 2007 The Authors Journal compilation © 2007 Blackwell Munksgaard.
