The instruments of a mariachi band

Strings, brass, and voices each play a clear role. Violins usually carry the melody and the sweeping introductions that make mariachi so recognizable.

The string section

Violins usually carry the melody and the sweeping introductions that make mariachi so recognizable. A full ensemble often has several violins playing together, sometimes in harmony.

The Spanish guitar adds chords and rhythm, and in some groups a folk harp adds bright, rippling notes.

The rhythm engine

Two instruments give mariachi its bounce. The vihuela is a small, round-backed guitar with five strings, strummed in quick patterns. The guitarrón is a large, deep-bodied bass guitar that sets the pulse and the bass line.

Together they drive the rhythm so firmly that a mariachi can play without a drummer.

Trumpets and voices

Trumpets became a standard part of the ensemble in the twentieth century, adding brilliance and power. Most groups use two trumpets that answer the violins or play in harmony.

Nearly every musician also sings, so the band can shift from a solo voice to a full chorus within a single song.
