2. Music is an art form in which the medium is sound organized in time.

The word derives from Greek μουσική ( mousike ), "(art) of the Muses".

3. Hip hop music , also referred to as rap music , is a music genre typically consisting of a rhythmic vocal style called rap which is accompanied with backing beats. Hip hop music is part of hip hop culture, which began in the Bronx, in New York City in the 1970s, predominantly among African Americans and Latinos. The term rap is often used synonymously with hip hop music . Chamillionaire – Turn’it up

4. Jazz is an American musical art form which originated in the beginning of the 20th century in African American communities in the Southern United States from a confluence of African and European music traditions. The style's West African pedigree is evident in its use of blue notes, improvisation, polyrhythms, syncopation, and the swung note. John Coltrane - Alabama

5. The Blues is a vocal and instrumental form of music based on the use of the blue notes. It emerged as an accessible form of self-expression in African-American communities of the United States from spirituals, work songs, field hollers, shouts and chants, and rhymed simple narrative ballads. The use of blue notes and the prominence of call-and-response patterns in the music and lyrics are indicative of African influence. JB Lenoir – Alabama Blues

6. Heavy metal (often referred to simply as metal ) is a genre of rock music that developed in the late 1960s and early 1970s, largely in England and the United States. With roots in blues-rock and psychedelic rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Metallica – St. Anger

7. Salsa music is a diverse and predominantly Latin American Caribbean genre that is popular across Latin America and among Latinos abroad. Salsa incorporates multiple styles and variations; the term can be used to describe most any form of popular Cuban-derived genre, such as chachachá and Son. Most specifically, however, salsa refers to a particular style developed in the 1960s and '70s by Cuban and Puerto Rican immigrants to the New York City area, and stylistic descendants like 1980s salsa romantica. Hector Lavoe & Willie Colon – Todo tiene su final

8. Country music is a blend of popular musical forms originally found in the Southern United States and the Appalachian Mountains. It has roots in traditional folk music, Celtic music, gospel music, and old-time music and evolved rapidly in the 1920s. Janis Joplin – Mercedes Benz

9. Pop music as a genre features a noticeable rhythmic element, melodies and hooks, a mainstream style and conventional structure. The term is also sometimes used to refer to any piece of music that appears in popular record charts due to a high number of sales and/or airplay. In opposition to music that requires education to appreciate, a defining characteristic of pop music is that anyone is able to enjoy it. Artistic concepts such as musical form and aesthetics are not always a concern in the writing of pop songs, the primary objectives being audience enjoyment and commercial success. Beyoncé – If I were a boy

10. Punk rock is a rock music genre that developed between 1974 and 1976 in the United States, the United Kingdom, and Australia. Rooted in garage rock and other forms of what is now known as protopunk music, punk rock bands eschewed the perceived excesses of mainstream 1970s rock. They created fast, hard-edged music, typically with short songs, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY (do it yourself) ethic, with many bands self-producing their recordings and distributing them through informal channels. Tokio Hotel – Through the Monsoon
