Introduction
I chose this theme because I love music, music is an important part of my life. I can find a lot of feelings, colors, flavours with the different kind of music. All my life I have been related with music, a lot of members on my family are musicians and this is the reason I like music.
The music has many eras, since Prehistory to our days, all this music is very important, we can see the progress in genres like rock, tropical and latin.
But forgetting the old eras I´m going to talk about modern music, I decided to talk about modern music because it´s the music I have been listening all my life and I like it.
Modern Music
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 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.
How to define music has long been the subject of debate; philosphers, musicians, and, more recently, various social and natural scientists have argued about what constitutes music. The definition has varied through history, in different regions, and within societies. Definitions vary as music, like art, is a subjectively perceived phenomenon. Its definition has been tackled by philosophers of art, lexicographers, composers, music critics, musicians, semioticians or semiologists, linguists, sociologists, and neurologists. Music may be defined according to various criteria including organization, pleasantness, intent, social construction, perceptual processes and engagement, universal aspects or family resemblances, and through contrast or negative definition.

To people in many cultures, music is inextricably intertwined into their way of life. 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. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."
Music is found in every known culture, past and present, varying wildly between times and places. Scientists now believe that modern humans emerged from Africa 160,000 years ago. Around 50,000 years ago these 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 must have been present in the ancestral population prior to the dispersal of humans around the world. Consequently music must have been in existence for at least 50,000 years and the first music must 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.
Classical music is a broad, somewhat imprecise term, referring to music produced in, or rooted in the traditions of art, ecclesiastical and concert music. A music is classical if it includes some of the following features: a learned tradition, support from the church or government, or greater cultural capital. Classical music is also described as complex, lasting, transcendent, and abstract. In many cultures a classical tradition coexisted with traditional or popular music, occasionally for thousands of years, and with different levels of mutual borrowing with the parallel tradition.
The field of 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).
The first studies of Western musical history date back to the middle of the 18th century. G.B. Martini published a three volume history titled Storia della musica (History of Music) between 1757 and 1781. Martin Gerbert published a two volume history of sacred music titled De cantu de musica sacra in 1774. Gerbert followed this work with a three volume work Scriptores ecclesiastici de musica sacra containing significant writings on sacred music from the third century AD onwards in 1784.
In the twentieth century, the work of Johannes Wolf and others developed studies in Medieval music and early Renaissance music. Wolf's writings on the history of musical notation are considered to be particularly notable by musicologists. Historical musicology has played a critical role in renewed interest in Baroque music as well as medieval and Renaissance music. In particular, the authentic performance movement owes much to historical musicological scholarship. Towards the middle of the twentieth century, musicology (and its largest subfield of historical musicology) expanded significantly as a field of study.
Concurrently the number of musicological and music journals increased to create further outlets for the publication of research. The domination of German language scholarship ebbed as significant journals sprang up throughout the West, especially America.
According to Richard Middleton, the strongest criticism of (historical) musicology has been that it by and large ignores popular music. Though musicological study of popular music has vastly increased in quantity recently, Middleton's assertion in 1990-- that most major "works of musicology, theoretical or historical, act as though popular music did not exist" -- holds true. Academic and conservatory training typically only peripherally addresses this broad spectrum of music’s, and many (historical) musicologists who are "both contemptuous and condescending are looking for types of production, musical form, and listening which they associate with a different kind of music...'classical music'...and they generally find popular music lacking".
Notational centricity also encourages "reification: the score comes to be seen as 'the music', or perhaps the music in an ideal form." As s
· It is true that international music is now in hearts of most of the young people all over the world, and traditional music of one’s country is not given much importance. As I said music is music let it be international or traditional and all efforts should be made to preserve one’s own traditional music.
