Also, I've played a fair amount of music by Mexican (and other Latin American) composers, because Camellia Symphony has an Argentine conductor. The first concert I played in that orchestra featured all composers from Spanish-speaking countries (not all Latin American, as there was one Spanish composer) and I later played an all Latin American concert.

Other than José Pablo Moncayo's "Huapango", which I mentioned in another thread, here are other Mexican pieces I can remember playing.

Danzón No. 2, by Arturo Márquez, which is probably the single most performed piece by any Mexican composer:

Sinfonía India, by Carlos Chávez, which is based entirely on Native American folk songs that Chávez recorded in northern and western Mexico.

Chacona a Chávez, by Enrique Diemecke, based on a chaconne by Handel. This piece was commissioned for the 100th anniversary of Chávez's birth. In the 1930s Chávez produced one of the best known modern orchestrations of Baroque music, a chaconne by Buxtehude. Diemecke chose to pay homage to Chávez by following in his footsteps and orchestrating another Baroque chaconne in a "Mexican" style.

Marcha de Zacatecas, by Genaro Codina, sometimes referred to as Mexico's second national anthem. You can definitely hear Central European elements in this. Codina was mainly a composer of dance music, and was from the state of Zacatecas, part of the northern region where German and Czech folk music were influential.
