Opera singers are trained vocalists who perform in operas, a theatrical art form that combines singing, acting, and orchestral music. They typically possess strong vocal techniques and the ability to project their voices without microphones, allowing them to be heard over an orchestra. Opera singers often specialize in different voice types, such as soprano, mezzo-soprano, tenor, and bass. These performers usually undergo extensive training, often attending music conservatories or universities to refine their skills. They interpret characters through their singing and acting, bringing stories to life on stage. Famous opera singers, like Luciano Pavarotti and Maria Callas, have made significant contributions to the art form and are celebrated for their exceptional talent.
