Mariachi is a genre that developed in western Mexico
when the music from Spain collided with that of the American natives.
It is defined by so much more than its instrumentation:
settings, costuming, singing and dance styles, etc.
However, its instrumentation is indeed distinctive. . . .
The style is most importantly supported by the guitars.
These, of course, are Spanish guitars, which differ from what we usually call acoustic guitars.
Other guitar variations (not displayed here) are the five-stringed vihuela
and the acoustic six-stringed bass, called guitarrón.
The next most common instrument is the violin.
It is remarkable how this "classical" instrument is an important part of so many "folk" styles.
The mariachi violinist uses a lot of open-string notes and long bowing.
But musical ornaments (turns, etc.) are also important, notably the glissando.
Many mariachi bands are dominated by the trumpet.
This was the inspiration behind Herb Alpert forming the Tijuana Brass.
Mariachi trumpet players have a very bright sound and use a lot of vibrato.
They also use distinct patterns of articulations.
Most mariachi playing is done without any percussion instruments.
The percussive effect is produced by the style of guitar playing.
However, some bands have added percussionists to their lineups.
Here are some of the fun-to-play Latin percussion instruments.
Believe it or not, some school officials ban the wearing of mariachi costumes
by Latino students because they say it's offensive to Latinos. Hmm.
I think I'll ban plaid skirts at my school, so as not offend Scots.
