On August 27, 1971, under the initiative of Enrique Bátiz Campbell and the government of the State of Mexico, the Symphonic Orchestra (OSEM) of this state was founded, with the purpose of spreading music as an art as a means of creating union and identity among the citizens of the state.

Located in the city of Toluca, and having as its home hall the Sala Felipe Villanueva, the Orchestra has been characterized since the start by its endeavor to carry its message to all the municipalities of the state, to all corners of the country.
