Looking for the title of this may be Mexican music

Question

I think I had played this music 25 years ago, when I was living in Mexico. It sounds like a Mexican traditional song, or Mariachi.

I can only remember the phrase written in the score bellow. It's likely that whole music is constructed of similar phrases. I played it with my violin (with few others from violin class), but it is possible that this is usually played by a guitar or trumpet part. I don't know if it has singing on this music.

Key might not be correct.

Answer 1

You are looking for the crown jewel of the Mexican repertoir: Huapango, composed by José Pablo Moncayo.

The violins start playing the theme of your first two lines right after the 1 minute mark in this performance.
