According to the principles of music therapy you can change your mood, as well as calm your body, by listening to a certain number of songs in a certain order or sequence, so as to transport you, step by step, into whichever mood you want to go to.
Iso-moodic principle is “a technique by which music is matched with the mood, then gradually altered to affect the desired mood state. This technique can also be used to affect physiological responses such as heart rate and blood pressure.”
William B. Davis, Kate E. Gfeller, Michael Thaut, authors of An Introduction to Music Therapy.
To some people this idea may seem somewhat counter-intuitive. They may ask, “If I’m in a bad mood and I want cheering up, why would I want to play a song that is miserable? Why not play something that is happy?” To which the answer would be: playing a happy song when you are miserable will not have any meaningful effect. Only by matching your mood do you then get to alter it, step by step.
