The Brazilian seven-string guitar ({{langx|pt|violão de sete cordas}}) is an acoustic guitar used primarily in [[choro]] and [[samba]]. It was introduced to Brazil in the late 19th century as a steel string guitar. The style of "baixaria" counterpoint and accompaniment technique was developed throughout the 20th century, especially by [[Dino 7 Cordas]] and [[Raphael Rabello]]. In the early 1980s, guitarist [[Luiz Otavio Braga]] had a nylon string version made, and this has become the norm for most contemporary solo musicians such as [[Yamandu Costa]].

The Brazilian seven-string guitar is typically tuned like a classical guitar, but with an additional C below the low E as follows: C2 E2 A2 D3 G3 B3 E4; although some musicians tune the C down to a B resulting in: B1 E2 A2 D3 G3 B3 E4.
