The opera is a musical-dramatic genre in which the whole story is expressed by orchestra accompanied by a ballet. Speaker voices are divided in depth by depth. The male voices are (from the deepest): bass, baritone and tenor; female voices are: alt, mezzo-soprano and soprano. The singer’s number in which characters express our feelings and moods is called aria. Recitativ is a relatively monotonous dialogue. The essence of the opera is the mutual harmony of literary, musical and visual expression, which makes the opera undoubtedly one of the cultures of human culture.
