Your heart rate, or pulse, is the number of times your heart beats per minute. Everyone has a different heart rate depending on who they are. “As you age, changes in the rate and regularity of your pulse can change and may signify a heart condition or other condition that needs to be addressed,” said Richard Stein, M.D., professor of medicine and cardiology at the New York University School of Medicine in New York City and a volunteer for the American Heart Association. To get a very accurate reading put your finger on one of the following places:
 * wrists
 * inside of your elbow
 * side of your neck
 * top of the foot ( All About Heart Rate Plus)

Pulse and heart rate are actually two different things. Heart rate is how many times the heart beats in x amount of time. Pulse is "the regular throbbing of the arteries, caused by the successive contractions of the heart, especially may be felt at an artery, as at the wrist." (Dictionary.com)

Mostly the people that take heart rates are athletes to get a lot of efficiency out of the workouts. (Nordqvist, Christian.) For a human aged 18 or more years, a normal resting heart rate can be anything between 70 and 110 beats per minute. (Seth Meshko)

A normal persons heart beats about 40 million times a year."In 1918, Hyde and Scalapino1 reported that minor tones increased pulse rate and lowered blood pressure, whereas “stirring” music increased both blood pressure and heart rate." (Bozeman) “The idea that music has an effect on heart rate and blood pressure has existed for some time” Luciano Bernadi says. In 1918 a science experiment says that music raises blood pressure. The influence of the rhythm could raise up the heart rate. (Circulation)
