Flamenco is much more than a style of music, it has it's own dialect, it's own traditions and rules, it is a living art, a way of life, a way of perceiving and interpreting daily existence.
Nothing is written down.
Flamenco is an oral tradition, only the music for solo guitar has been successfully transcribed. Which implies that all others are not serious Flamenco. The developments of the past 30 years or so, are now called simply Flamenco Nuevo. And the older generation laments that the roots are being lost, that Flamenco is no longer what it was, well neither is society.
