In 1973 José de Udaeta organised the first International Summer Academy for Spanish Dance in Sitges, Spain; during the following 22 years, this summer academy became the most important institution worldwide where the next generation of dancers could obtain tuition in all aspects of Spanish dance. José de Udaeta managed to gather round him an internationally renowned team of teachers to disseminate the rich cultural Spanish heritage to the pupils who had come from all over the world to these summer academies.
In the 1980s José de Udaeta did lecture demonstrations with his castagnets in a number of famous American universities.
Since 1977 José de Udaeta teaches the playing of the castanets as a concert instrument, following the method and notation of Emma Maleras, mainly in the various important ballet schools in Germany.
