An opera singer is a vocalist who performs in the genre of opera, a theatrical art form that combines singing, acting, and orchestral music. These singers are trained to project their voices without microphones, often performing in large theaters. They typically specialize in various vocal ranges, such as soprano, mezzo-soprano, tenor, baritone, and bass, each suited for different roles in operatic productions. Opera singers often undergo extensive training in vocal techniques, languages, and acting to effectively convey the emotions and stories of the characters they portray. They may perform in various styles, including classical and contemporary operas, and often collaborate with conductors, musicians, and stage directors to create a cohesive performance.
