was a Spanish Basque composer who was a key player in 20th-century Spanish and Basque music. His style fits into the late Romantic idiom, directly inherited from Wagner, and with a strong influence from Basque culture. Among his best-known works are the zarzuela El Caserío, the opera Amaya, the orchestral work Ten Basque Melodies and his organ works, where the Triptych of the Good Shepherd can be highlighted.
Guridi was born in Vitoria-Gasteiz into a family of musicians. His mother, Maria Trinidad Bidaola, was a violinist and his father, Lorenzo Guridi, was a pianist (Menéndez and Pizà 2001). After completing his early studies with the Piarists and the Jesuits of Zaragoza he moved to Madrid, where he received lessons from Valentín Arín. Later, in Bilbao, he received violin lessons from Lope Alaña, who introduced him to the society called "El Cuartito", and studied harmony with José Sáinz Besabe (Menéndez and Pizà 2001). On 28 January 1901 he gave his first public concert with the Philharmonic Society of Bilbao. At the age of 18 he enrolled in the Schola Cantorum in Paris, studying organ with Abel Decaux, composition with Auguste Sérieyx, and fugue and counterpoint with Vincent d'Indy. Here he met Jose Maria Usandizaga, with whom he developed a deep friendship.
He then moved to Brussels, where he studied with Joseph Jongen and in Cologne with Otto Neitzel, following the recommendations of Resurrección Maria de Azcue. In June 1912 he was appointed director of the Bilbao Choral Society. In the same year his friend Usandizaga died.
In 1922 he married Julia Ispizua. The couple had six children: María Jesús, Luis Fernando, María Isabel, Ignacio, Julia, and Javier. In 1944 he began working at the Madrid Conservatory, where, years later, he became director.
He died suddenly on 7 April 1961 at the age of 74 years in his home on Sagasta Street in Madrid.
Strongly influenced by Richard Wagner and other late-Romantic musicians, he found inspiration in the roots of Basque folklore in his first scores, and which later give body and soul to his compositions. Guridi produced copiously in a huge range of genres. From chamber music (string quartets), vocal and choral compositions, orchestral works, liturgical and concert pieces for the organ, operas (Mirentxu and Amaya) and zarzuelas (El Caserio, La Meiga, etc.). Among his works are: El Caserio (1926), Diez melodias Vascas (1940), Así cantan los chicos (1909), Amaya (1920), Mirentxu (1910), Una aventura de Don Quixote (1916), La Meiga (1929), Seis canciones castellanas (1939), Pyrenean Symphony (1945), and Homenaje a Walt Disney, for piano and orchestra (1956).
