Tango is a style of music in 24 or 44 time that originated among European and African immigrant populations of Argentina and Uruguay. It is traditionally played on a solo guitar, guitar duo, or an ensemble, known as the orquesta típica, which includes at least two violins, flute, piano, double bass, and at least two bandoneóns. Sometimes guitars and a clarinet join the ensemble. Tango may be purely instrumental or may include a vocalist. Tango music and dance have become popular throughout the world.

The double bass, also known as the upright bass, the acoustic bass, or simply the bass, is the largest and lowest-pitched chordophone in the modern symphony orchestra. Similar in structure to the cello, it has four or five strings.
