Jazz music was born from a mix of European and African music traditions at the beginning of the 20th Century among African American communities in southern areas of the United States. African undertones are evident in the mixture of blue notes, polyrhythms, improvisation, syncopation, and the swing note.
Metal music is characteristic of powerful and loud bass drums and aggressive electric guitars. It was developed in the United Kingdom in the 1960s and early 1970s and also in the United States. The words are usually about provocative and controversial themes. Metal music fans are referred to as head bangers and metal heads.
Rap music originated among African-Americans’ inner-city street culture in the 1970s. Rap is considered as a mainstream type and is popular among people of all ages and background around the world.
Rap music is generally not sung. The words are spoken with a backdrop of music borrowed from soul, funk and rock pieces. Musicians remix sounds, and rhythms with their own innovations and synthesized musical elements.
