Full Credit Presentation defines the three main roles of music discussed in the unit, giving an example for each.

Music is the art of organizing sound structures in time. One of the fields of fine arts that affects the human psyche through sounds.

Sound structures consist of sets of acoustic waves with deliberately selected frequencies and amplitudes and the silence in between. One of the goals of music is self-expression and the transmission of subjective feelings of the composer or performer, which influences the feelings, reactions and consciousness of the listener who processes these experiences in a completely individual way. It differs from human speech by a much greater abstraction of the content conveyed and the use, in addition to the human voice, of musical instruments and all electronic, natural and inarticulate sounds.

Music is one aspect of human culture. It can be assumed that music has always accompanied people at work, playing, resting and in rituals, and probably from the very beginning it was also associated with dance and words. At first, music served a practical purpose - it helped in teamwork, was a form of communication, and later it also became an element of collective identity. Over time, it developed as one of the branches of art.
