José Gonzalo Zulaica (also known as José Antonio de Donostia;^[1] 10 January 1886 – 30 August 1956), better known by his pen name Aita Donostia (lit. 'father Donostia', referring to the Basque name of San Sebastián), was a Spanish and Basque musicologist and composer.^[2]

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.
