One could say simply that an opera singer, well, sings. However, there is much more involved in an opera-singing career than merely vocalizing. An opera singer will typically need to memorize a variety of different musical numbers. Because many of the classical operas were written in foreign languages, particularly Italian, an opera singer should also be fluent in a number of different languages. As for singing, an opera singer is typically required to practice for several hours each day. In some instances, these singers will practice nearly every day of the week, for weeks or months at a time.
