♫ Kenneth Bager - Fragment Eight (The Sound of Swing)

Here is an artist whose existence I just found out.  In 1994, he released a compilation called "Music for Dreams" featuring, among others, Peter Gabriel and Michael Nyman. Bager received his breakthrough with the release of his critically acclaimed debut album "Fragments From A Space Cadet" in 2006, for which he received the Danish Statens Kunstfond award. This is a familiar song, I think.. Enjoy! :-)

Let 's get started with -What music is?-

  - Music is an art form whose medium is sound and silence. Its common elements 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 μουσική (mousike; "art of the Muses").

    The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts", music may be classified as a performing art, a fine art, and auditory art. There is also a strong connection between music and mathematics.

    To many people in many cultures, music is an important part of their way of life. Ancient Greek and Indian philosophers 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. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound." Musicologist Jean-Jacques Nattiezsummarizes the relativist, post-modern viewpoint: "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." -
