David Zaizar was a Mexican ranchera singer and actor who appeared in many Mexican films. He was active from the 1940s up until his death in 1982 due to a respiratory infection. What earned him the title of the "Rey del Falsete" or "King of the Falsetto" was the fact that he displaced Miguel Aceves Mejia, who had the title until Zaizar's appearance on the ranchera music scene. His voice is known today as having had beauty, interpretative quality, tone, and plenty of feeling and emotion. Initially, he joined forces with his brother, Juan Zaizar, with whom he formed a duo. Prior to this, they had both been working on individual projects, especially Juan, who was a renowned composer and singer. They had only sung together for very special occasions, like their tribute to honor the famous ranchera composer, also from Jalisco, Pepe Guizar. Out of this union came the famous duo, Los Hermanos Zaizar (the Záizar brothers). Like most Mexican folk songs, the majority of those interpreted by David that we have left today are about lost loves, unfaithful women, Mexico and its people, and several other topics commonly present throughout ranchera music.
