That's it, you spelled it correctly. Ma-ree-ah-chee (trying to spell it how it sounds, in English).
It used to be thought that the word came from the French word for marriage -- Mariachis were the musicians who played at weddings. Mariachi was the name of the style of music that they played. But the pronunciation got corrupted in Mexico, several centuries ago, making "ma-ree-aj" into "Ma-ree-ah-chee".
Nowadays there's a rival theory that "Mariachi" is a corruption of a word in one of the native Mexican languages. It may refer to some of the types of wood that their instruments are made out of.
Whatever the origin of the word, it's one of the best of Mexican culture, loud, bright, bold and thoroughly Mexicano.
