Music is a time art, because it does not occupy space, but is only expressed within a certain time limit and through a certain period of time. Paintings, sculptures, buildings, etc. must occupy a certain space, so they belong to space art. Synthetic art is art that requires both time and space in its expression.

Music is the art of time. After every line is sung, there is no way to make up for it. You must enter the best state from the beginning, use the power of your entire body, and perfectly lift and expand the flow of the sound in time-until the end.
