Corridinho

The corridinho is a form of Portuguese folk dance, namely in the Algarve region. The origin of the dance itself is unclear and believed older, although it gained popularity in the 1800s. The name derives from correr, to run which partly describes this type of dance. The dance was performed in a round (dança de roda) in the open air. The oldest musical instruments recorded were small flutes or fifes  and harmonicas,  until the accordion was implemented and dominated ever since.
