Since many of the most popular operas are in foreign languages, opera students should also become fluent in these languages. Italian, for instance, is one of the most common languages for operas, as is German and French. Although fluency in these languages is not required, it will help an opera singer qualify for many more roles. An opera singer’s salary can be somewhat difficult to determine at times. More talented opera singers performing in large opera houses or opera companies, for instance, will typically make higher salaries. Many opera singers who are employed by established opera houses or companies also typically have set salaries, which are bound by contracts.
