The requinto guitar is a six-string nylon guitar with a scale length of 530 to 540mm, this is about 18% smaller than a standard guitar scale (650 to 655mm).
Many requintos have cutaways. Requintos made in Mexico typically have a deeper body than a standard guitar (110mm as opposed to 105mm). In Mexico,
the requinto is typically used in a "trio romantico", which includes the use of two other guitars along with the requinto.
