In conclusion, I thought The song was to drain the tension in mind. Through melody and rhythm called out to help manage the lungs. The increased lung capacity . Refreshing body strength. And enhance self-confidence . We should sing with emotion at the time and in the right place. Proper place in the music . This helps to make music more melodic . Create the listener the mood I like a quiet place . No noise from outside. Temperatures cool beauty of the room is a mess and so on.
Reasonable period of time . If you listen to music a lot . Can cause fatigue tired tired because a lot of work to get nervous . Should stop and listen to music , but rather than listening to music for hours .
