Affects of music?
You are experiencing affects of music when you listen to pleasant sounds that cause you to shut down emotionally to the point where you cannot define your feelings. Affect is the reason why we enjoy the types of music that we like. Some people are touched by specific styles of music as it heightens their emotions. Others may use music to help them express their true inner feelings. No matter what reasons people come up with, music preferences are determined by personal interpretations of the music, what it does for us, and is experienced by it.
anything can affect HR, thinking about your HR affects your heart rate. Music definitely can. Music can't do it all by itself, the way it works is music affects your mood and THAT in turn affects your HR. If music makes you angry or upset your HR will rise and if the music soothes you or relaxes you, then your HR will fall.
