This Sunday night on “The Lost Chord,” it’s all Mexican music on the eve of Cinco de Mayo. We’ll hear a fun solfeggio piece (“Sol-fa de Pedro”) by the baroque composer Manuel de Zumaya. Zumaya, born in Mexico around 1678, is believed to have written the first opera in the western hemisphere. He became chapel master of Mexico City Cathedral in 1715.

Blas Galindo is best known in the United States for the evocative “Sones de Mariachi.” But he composed over 150 works, including seven ballets. One of these was “La Manda,” or “The Vow,” written in 1951. The scenario is a bit of downer, about an ailing wife on a pilgrimage who believes she is losing her husband to another woman, but the music is full of distinct nationalist character.

Manuel Ponce is one of Mexico’s most famous composers. He’s probably best recognized for his guitar music, thanks to his association with Andrés Segovia. Less frequently heard is his Violin Concerto of 1942. We’ll have the soloist who gave the work its premiere, Henryk Szeryng, in a recording made some forty years later.

Pour yourself a Corona, mix up some guacamole, and enjoy “Mayo My,” Mexican music for Cinco de Mayo, Sunday night at 10 ET, with a repeat Thursday night at 11, or listen to it later as a webcast at http://www.wwfm.org.
