Pop emerged in the United States in the 50s. The musical style is marked by the conservation of the formal structure of the music: “verso – refrain – verso”, performed in a sensitive and melodic way, normally assimilated by a large audience. Still characteristic of Pop singers are the habit of making extravagant concert scenarios, a lot of dance and countless other craftsmen.
The 90s were marked by boy bands and girl groups (groups of 5 to 6 boys or girls dancing vocalists who took turns on vocal solo). Some examples of such bands that burst at the time are Spices Girls and Backstreet Boys. Also in this period, we can mention the emergence of pop princesses, such as Mandy Moore, Britney Spears, Beyoncé, Jessica Simpson and Christina Aguilera, and the phenomena of Latin Pop Ricky Martin, Jennifer Lopez, Shakira and Enrique Iglesias.
