Francisco Llácer Pla (Valencia, 1918 - Valencia, 2002) was a Spanish composer and choral conductor. He was one of the first Valencian composers who assimilated the postwar avantgarde approaches, combining it with lyricism and echoes of the Valencian folklore. Tomás Marco wrote: Llácer Pla offers a new, suggestive vision of a form of musical nationalism from a new, progressive perspective. A professor at the Valencia Conservatory, several of his progressive works are based in his harmonic investigations, such as his concept of heptafonism and his theory of the "balanced chord", based on the double sense of the sonorous bodies' resonance.
