For only 80 Euros learn the basics of the Flamenco guitar (4 classes each 2 hours long). Yo will be able to play nonrhythmic Flamenco styles such as Granaina and Taranta. And get an introduction to other styles of Flamenco such as Tangos, Soleá etc. Yo will learn the basic techniques needed for playing Flamenco and other genres. If you pretend to buy a guitar in Barcelona I can help you choosing the best one for you.
