José Gonzalo Zulaica (also known as José Antonio de Donostia; 10 January 1886 â 30 August 1956), better known by his pen name Aita Donostia (, referring to the Basque name of San Sebastián), was a Spanish and Basque musicologist and composer.
He was born on 10 January 1886 in San Sebastián. From 1936 to 1943, he was in exile in France.
His most popular work is the Basque Preludes, a set of fifteen piano pieces inspired by Basque traditional music, arranged in a very romantic way, that is reminiscent of Robert Schumann's and Edvard Grieg's styles.
