In the 1930s and 1940s he played throughout the Rio Grande Valley with a group whose instruments included the accordion, tambora , guitar, and tololoche . In 1947 he had another opportunity to record. His first recordings were the polkas “La Burrita” and “La Pajarera” on the Mira label, the precursor of Falcon Records. Following his first recordings and throughout the 1950s, he toured Texas and the Southwest playing at dances that would often begin at eight in the evening and continue until six in the morning. Pedro’s favorite musical styles included tangos, boleros, polkas, redovas , and valses. In retrospect he said his favorite music style was the tango, and his favorite tango was “Canto Por No Llorrar” (“I Sing Rather Than Cry”). Pedro Ayala also played with many orchestras such as Eugenio Gutierrez, Beto Villa, and Isidro Lopez. He traveled with his family as a migrant worker in 1959 and worked in farming fields across the northern United States, including Michigan and Ohio, as well as west to California. Ayala continued to perform at dances during this time.
He recorded several albums in the 1960s and 1970s including Viva Mi Desgracia (1968) and Adios Mama Carlota (1973). In the 1980s he lived with his wife Esperanza and sons in Donna, Texas. In 1988 the National Endowment for the Arts honored Ayala as a National Heritage Fellow. He died on December 1, 1990. A compilation of his recordings was released on Arhoolie Records in 2001 and titled El Monarca Del Acordeon. He was inducted into the Tejano R.O.O.T.S. Hall of Fame in 2004.
