Argentine tango is known for its intricate rhythms and irregular tempo, but also for its passionate melodies. This is what makes this dance so sensual and the music so intoxicating! Although the bandoneón is now tango’s most famous instrument, the guitar is the instrument that gave birth to tango. When tango emerged in Argentina in the late 19th century, the guitar formed the rhythmic basis of the first instrumental trios, which also included a violin and a flute.
