The acclaimed musician has lent his voice and his melodies to the campaign in a video released Wednesday.
Before he begins singing, Fernández tells Latinos their voice is their vote and that "together we can." The video then shows clips of Clinton campaigning with Latinos across the country with Fernández singing in the background.
"Hillary, we are with you," he says in the corrido. "With our vote you can count on. You are going to be our voice once you are in the presidency."
At one point, Fernández - who came out of retirement to compose the corrido for Clinton - makes a reference to Donald Trump's insults to Mexican immigrants but doesn't mention the Republican presidential nominee by name.
After he finishes the corrido, Fernández delivers a message to Clinton: "Mrs. Clinton, I'm here to ask you that when you get to the presidency, do not forget about my Mexican and Latin American brothers."
Fernández collaborated with the Latino Victory Project, which endorsed Clinton in February, to put the video together.
Martín Diego García, the group's director of campaigns, said in a statement that Fernández is "a true legend who has earned the respect and admiration of the Latino community in the United States."
"Vicente's call to action is a powerful reminder that Secretary Clinton is the only candidate who will respect and work with the Latino community, and he is proud to stand with her," García stated.
