In 1941, the group definitively integrated the trumpet into their musical interpretations. Miguel Martínez Domínguez was the first trumpet player for Mariachi Vargas de Tecalitlán; he is considered the creator of the mariachi-style trumpet as well as its best performer, teacher, and exemplar. In 1944, Rubén Fuentes, a classical violinist with no background in mariachi music, was asked by Silvestre to join the group. Fuentes joined as a violinist and took over as music arranger. Silvestre Vargas and Ruben Fuentes reorganized Mariachi Vargas de Tecalitlán and changed the group's sound. To overcome the unsavory connotations that the term "mariachis" had for the public in those days, the two leaders also updated the group's image by demanding professional presentation.
