1.- Flamenco guitars are lighter than classical guitars.
Many flamenco guitarists play standing, so they need a lighter guitar , that is why the woods used in the flamenco guitars are thinner than in the classical guitar. This lightness in addition to providing more sound projection to the guitar gives it more volume too.
2.- Flamenco guitar body is slightly narrower that the classical guitar body.
Perhaps for the same reason that some flamenco players need a more handily guitar they are made of a narrower body than classicals
3.- Flamenco guitars have lower string action and thinner necks than classical guitars.
The more percussive “toque” of the flamenco guitar technique and the fast “ligados” have made necessary to make lowered action guitar necks for the flamenco guitar, some slight “buzzing” is accepted and even desired in flamenco Technique.
4.- Most flamenco guitars use different woods for the back and sides.
The most used wood for the flamenco guitar top is spruce for its aggressive tone, the choice for the back and sides have traditionally been cypress although recently is being used Rosewood in the “Flamenca negra”.
Of course, i’m only talking about the most common differences in most flamenco guitars, some luthiers have special models with many different types of woods and other features.
An remember, a flamenco guitar is not only a guitar to play flamenco, it’s a wonderful nylong string guitar for those guitarists who are looking for a comfortable, great sounding guitar.
