What is Music to You ?

Music generally refers to pleasing sound perceived by humans. The same sound can be annoying to another person, he will call it disturbance.
So, music is a matter of personal choice. Human pschology is different for every person. His or her interest in music will be diferrent from others altogether.

Music is an art form in which the medium is sound organized in time. Common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture.
The word derives from Greek (mousike), "(art) of the Muses".

To many, music is a way of life, such as it is to the Native Americans, who use their music to pray.
Many still use this practice today, who have found their hearts in the melodies. Greek philosophers and ancient Indians defined music as tones ordered horizontally as melodies and vertically as harmonies.

Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to, but the opinion of the listener does not necessarily help music theorists formulate a precise definition of music.
Like the notion that visual arts must be beautiful to behold, the tacit notion that music need be pleasant to listen to has been questioned.

20th-century composer John Cage was explicit that any sound can be music, saying, for example, "There is no noise, only sound." According to musicologist Jean-Jacques Nattiez, "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'.
