Does the style of music you listen to change your blood pressure? Research suggests music can lower blood pressure and reduce stress. But not all genres may have the same effect. You take each participant's resting blood pressure first. Then you play songs from different genres one at a time. After each song you measure blood pressure again. You repeat this with at least six participants across styles like rock, rap, jazz, classical, and reggae. Compare the readings to see which genre raises or lowers blood pressure the most.
