After establishing the School of Hernani, a steady expansion of txalaparta ensued in the 80s among younger generations and out to other regions of the Basque Country. The Txalaparta Festival was established in 1987, adding to the interest for the instrument and acting as a showcase for fresh trends. Josu Goiri should be cited here, from Arrigorriaga, who adopted a fairly mystical approach on the instrument and has released several books on the topic. Another significant couple that got together in the 80s is Gerla Beti, standing for Perdi and Ruben, from Araia. They started to try new materials with the txalaparta.
