Music is an inevitable art with sound as a medium. Common elements (pitch, rhythm, dynamic, tempo, meter and the sonic qualities of timber and text) are the quintessence of music and it’s impossible to compose a groovy music composition in the absence of any of the element.

The definition of Music also varies from culture to culture and the social context. Both, the Greek as well as the Indian philosophers defined music as tones ordered horizontally as melodies and tones ordered vertically as harmonies. However, during the 20th century, John Cage came up with a new philosophy that any sound can be music, even noise is a form of music and that entirely depend on us, how we take the same. 

Jean Jacques Natties (a musicologist) said that "the border between music and noise is always culturally defined—which implies that, even within a single society, this border does not always pass through the same place; in short, there is rarely a consensus.... By all accounts there is no single and intercultural universal concept defining what music might be, except that it is 'sound through time.”
If we reckon today’s era then music is much more than just a form of entertainment.

May be you don’t know but music now days is being used as a therapy. Theoretically, music therapy is more of an interpersonal process in which a therapist ensures a better health and mental status to the clients by utilizing music and all of its facets (physical, mental, social, spiritual, emotional and aesthetic). So people must accept this fact that music not only appeals to our ears but also to our body and soul.
