HISTORY OF MUSIC
Music history, sometimes called historical musicology, is the highly diverse subfield of the broader discipline of musicology that studies the composition, performance, 
reception, and criticism of music over time. Historical studies of music are for example concerned with a composer's life and works, the developments of styles and genres (such as baroque concertos), the social function of music for a particular group of people (such as music at the court), or the modes of performance at a particular place and time (such as the performance forces of Johann Sebastian Bach's choir in Leipzig).
In theory, "music history" could refer to the study of the history of any type or genre of music (e.g., the history of Indian music or the history of rock). In practice, these research topics are nearly always categorized as part of ethnomusicology or cultural studies, whether or not they are ethnographically based.
The methods of music history include source studies (esp. manuscript studies), paleography, philology (especially textual criticism), style criticism, historiography (the choice of historical method), musical analysis, and iconography.
The application of musical analysis to further these goals is often a part of music history, though pure analysis or the development of new tools of music analysis is more likely to be seen in the field of music theory.
Some of the intellectual products of music historians include editions of musical works, biography of composers and other musicians, studies of the relationship between words and music, and the reflections upon the place of music in society.
Music is found in every known culture, past and present, varying wildly between times and places. Around 50,000 years ago, early modern humans began to disperse from Africa, reaching all the habitable continents. Since all people of the world, including the most isolated tribal groups, have a form of music, scientists conclude that music is likely to have been present in the ancestral population prior to the dispersal ofhumans around the world.
Consequently music may have been in existence for at least 50,000 years and the first music may have been invented in Africa and then evolved to become a fundamental constituent of human life.
A culture's music is influenced by all other aspects of that culture, including social and economic organization and experience, climate, and access to technology.
The emotions and ideas that music expresses, the situations in which music is played and listened to, and the attitudes toward music players and composers all vary between regions and periods. "Music history" is the distinct subfield of musicology and history which studies music (particularly Western art music) from a chronological perspective.
