Blue Tango, originalmente cargada por Rainer ❏.
Jazz is an American musical art form which originated around 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, call-and-response, improvisation, polyrhythms, syncopation, and the swung note of ragtime.
