Requinto

The requinto guitar has six nylon strings with a scale length of 530 to 540 millimetres (20.9 to 21.3 in), which is about 18% smaller than a standard guitar scale. Requintos are tuned: A2-D3-G3-C4-E4-A4 (one fourth higher than the standard classical guitar).

It was made popular throughout the 1940s by Mexican guitarist/vocalist Alfredo Gil of romantic music trio "Los Panchos." Requinto guitars are also used throughout Latin America.

Requintos made in Mexico have a deeper body than a standard classical guitar (110 millimetres (4.3 in) as opposed to 105 millimetres (4.1 in)). Requintos made in Spain tend to be of the same depth as the standard classical.
