Sad music can evoke positive emotion because it often reminds the listener of romance. Romantic emotions are often positive because they evoke feelings of happiness and being in love.
The music is also often more sad than the listeners own life. It may appear more tragic or unhappy than how individuals felt while listening to it. This then helps to provoke a contradictory emotion (happiness) than what is displayed in the music.
sadness experienced in one’s life and music is very different. If sadness is occurring in your own life it is a direct threat to your emotional well being. If experienced through music, however, there is no threat and it is much easier to enjoy the negative emotions.
“Emotion experienced by music has no direct danger or harm unlike the emotion experienced in everyday life. Therefore, we can even enjoy unpleasant emotion such as sadness. If we suffer from unpleasant emotion evoked through daily life, sad music might be helpful to alleviate negative emotion,”
