Alfredo Diez Nieto

Alfredo Diez Nieto (Havana, 1918) is a prominent figure in twentieth-century Cuban music, working as a composer, pedagogue, conductor and pianist. His output stands in continuity with a Cuban national tradition, into which he incorporated techniques characteristic of the twentieth century, and his name is associated both with composition and with music education in his country.

He began his training in Havana, where his teachers included Jaime Prats, Pedro Sanjuan and Roldán. In 1947 he travelled to New York to study at the Juilliard School of Music with Steuermann, Bernard Wagenaar and Fritz Mahler. As early as 1936 he was already teaching at Havana's conservatories. In 1959 he founded and directed the Alejandro García Caturla Conservatory, and he took part in organising specialist music education through the Popular Music Seminar. He taught in the band of the General Staff of the Revolutionary Armed Forces, at the National School of Arts and at the Instituto Superior de Arte. In 1965 he founded the Gonzalo Roig popular classical music orchestra, and he also conducted other symphonic ensembles in Cuba.

His catalogue encompasses orchestral, band, chamber and song music. Among his titles are the Sinfonía n.º 1 (1943) and Los diablitos (1969), a symphonic scene with a strong rhythmic pulse, inspired by a piano piece by Roldán, which evokes a dance of the íremes ñáñigos. In music for violin and piano, the Sonata para violín (1971) and the Gran sonata para piano (1978) stand out as demanding works for the performer, in which harmonic tensions do not obscure formal clarity or thematic definition.

His writings cover music theory, harmony and pedagogy. His legacy is seen above all in the training of generations of Cuban musicians and in the popularisation of classical music among general audiences.
