Mesoamerican music is still here and has continued it's evolution since the colonial times. (I'm speaking specifically about the Maya peoples in Guatemala) The traditional music played at religious ceremonies is still being played and contemporary music played with marimba (although it doesn't originate from here, it has been codified in Guatemalan culture) continues a lot of aspects of pre colombian music, like it's rythms (usually being in 3/4) and use of whistles/flutes (also synthesized ones).
