A requinto guitar is a smaller version of a classical guitar, with a scale length between 52-54cm. It is tuned a fourth higher than a standard classical guitar, to A2-D3-G3-C4-E4-A4. They often, but not always, have a cutout to reach the higher frets.

The requinto guitar is traditionally used in guitar orchestras, along with other sized guitars. The Requinto is also used in Mexican and Ecuadorian culture, and their national songs like pasillos and boleros, where the requinto plays a very big role in improvisation. The playing style of the requinto is very similar, in all the songs, and it is rarely played differently.

The requinto guitar is now especially popular in Mexico and elsewhere in Latin America. In Mexico it is used in trío romántico groups.

Requintos made in Mexico have a deeper body than a standard classical guitar (110 millimetres [4+1⁄3 in] as opposed to 105 millimetres [4+1⁄8 in]). Requintos made in Spain tend to be of the same depth as the standard classical.
