In 1975, Hauspoz Euskal Herriko Akordeoi Elkartea created the first accordion competition with the purpose of strengthening the accordion in every sense. Since then, the work and the help of everyone has led us to create a solid structure. This structure, reflected in a variety of categories, encourages the self-transcendence, and rewards as far as possible the work of students and teachers. Without any doubt, it is a rich experience for everybody.
