For this study the heart rates of twenty-two members of a college-level music appreciation class were recorded while students listened to the first movement of Beethoven's fifth symphony. The measurements were taken at three different times over a six-week period before, during, and after experimental treatment. Experimental treatment consisted of either audiotutorial tapes or repetitive listening sessions devised for specific musical-ability groups. The same test music was used throughout the entire study to determine the effects of learning and repetitive exposure on heart rate response. A control group had no further exposure to the test music during the study. Stable segments of the test music provoked tachycardia (elevated heart rate) in the subjects, while alternating segments produced bradycardia (lowered heart rate). Heart rate response to music was found to be linked with the presence or absence of learning.
