There are many depictions on painted vases and murals of the ancient Maya playing musical instruments. We also have been lucky enough to find remains of these instruments too.
Instruments could be made out of clay, wood, bone, shell and even reeds such as trumpets, drums, flutes, whistles and rattles. Music was played on many occasions, from ballgame events and warfare to festivities at court.
The image below depicts a conch shell that was used as a trumpet.
