A brief history of evolution

Evolution is a change in the genetic structure of a variety. For thousands of years during pre-scientific times the theory of evolution was unreal. The understanding of the universe was based only on the interpretation of paranormal concepts; God created Earth and made everything the way it is. People thought that to think differently would be impractical.

There were two long-standing planning that impeded the development of the concept of evolution. One would be the fixity of variety. The notion of Fixity of Species is that, “Species, once produced, can never modify.” This is a theory that is totally different to those of biological evolution. God created man as well as he is who he is. The non-living and whole worlds are fixed by creation.

Aspects of music

The traditional or classical European aspects of music often listed are those elements given primacy in European-influenced classical music: melody, harmony, rhythm, tone color or timbre, and form. A more comprehensive list is given by stating the aspects of sound: pitch, timbre, loudness, and duration. These aspects combine to create secondary aspects including structure, texture and style. Other commonly included aspects include the spatial location or the movement in space of sounds, gesture, and dance. Silence has long been considered an aspect of music, ranging from the dramatic pauses in Romantic-era symphonies to the avant-garde use of silence as an artistic statement in 20th century works such as John Cage's 4'33."John Cage considers duration the primary aspect of music because it is the only aspect common to both "sound" and "silence."

As mentioned above, not only do the aspects included as music vary, their importance varies. For instance, melody and harmony are often considered to be given more importance in classical music at the expense of rhythm and timbre. It is often debated whether there are aspects of music that are universal. The debate often hinges on definitions. For instance, the fairly common assertion that "tonality" is universal to all music requires an expansive definition of tonality.
