Guatemalan music comprises a number of styles and expressions. Guatemalan social change has been empowered by music such as nueva cancion, which blends together histories, present-day issues, and the political values and struggles of common people. The Maya had an intense musical practice, as documented by their iconography. Guatemala was also one of the first regions in the New World to be introduced to European music, from 1524 on. Many composers from the Renaissance, baroque, classical, romantic, and contemporary music styles have contributed works of all genres. The marimba, which is like a wooden xylophone, is the national instrument and its music is widely found in Guatemala. It has developed a large repertoire of very attractive pieces that have been popular for more than a century.
