Mexico is the world’s largest Spanish-speaking country, so it is no surprise that its music is strongly influenced by Spanish culture. Pre-Colombian native music and black slave influences are less strong than in other parts of Central America; stringed instruments and European church and classical singing have had the greatest impact on the development of Mexican music. Three main strands predominate. Most famous is Mariachi music, seen played by groups of wandering minstrels in major towns and tourist resorts all over Mexico. Wearing embroidered clothes and characteristic sombreros, they have become a cliché – but the quality of the playing should not be underestimated. In the complete Mariachi group today there are as many as six to eight violins, two trumpets, and a guitar – all standard European instruments. Then there is a round-backed guitar called the vihuela which, when strummed in the traditional manner, gives the Mariachi its typical rhythmic vitality; a deep-voiced guitar called the guitarrón, which serves as the bass of the ensemble; and a Mexican folk harp, which usually doubles the bass line but also ornaments the melody. While these three instruments have European origins, in their present form they are strictly Mexican.
