José Gonzalo Zulaica (10 January 1886 in San Sebastián, Spain – 30 August 1956), better known by his pen name Aita Donostia (Father Donostia or Father San Sebastian, because he was a priest born in San Sebastian, Donostia in the Basque language), was a Basque musicologist and composer. He was also known as José Antonio de Donostia.
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 reminds Robert Schumann's and Edvard Grieg's styles.
