Miguel Martínez Domínguez (September 29, 1921 in Celaya, Guanajuato – December 5, 2014 in Mexico City) was a Mexican musician, composer and arranger of mariachi, pioneer in the use of trumpet in this genre.

[1][2][3][4] From the middle of the 1930s[3] until 1940s, worked in the Plaza Garibaldi like musician in poor conditions, doing occasional substitutions with the mariachi of Concho Andrade that interpreted his pieces in the legendary bar Tenampa.

[3] In this group Martínez defined the function of the trumpet in the mariachi, instrument that was not usual in this gender until him.

His form to interpret created a unique and pioneer style that is the most imitated model until the actuality.

[6][7] Martinez reduced his professional activity from the 1970s after a dental problem derived from the trumpet use.
