Catterino Albertovich Cavos , also Katerino Al'bertovič Kavos (Russian: Катерино Альбертович Кавос , born: October 30, 1775, Venice, Italy – died: May 10 , 1840 St. Petersburg, Russia) was a Russianized Venetian immigrant, composer and conductor of the Imperial Theatres, who played an important role in the history of opera in Russia.

Cavos is celebrated in Russian musical history as the man who composed an opera Ivan Susanin (1815), 20 years before Glinka.

In music, a melody , also tune , voice , or line , is a series of linear events or a succession, not a simultaneity as in a chord (see harmony). However, this succession must contain change of some kind and be perceived as a single entity (possibly Gestalt) to be called a melody. Most specifically this includes patterns of changing pitches and durations, while most generally it includes any interacting patterns of changing events or quality. "Melody is said to result where there are interacting patterns of changing events occurring in time."

Change is necessary for events "to be understood as related or unrelated." Melodies often consist of one or more musical phrases, motifs, and are usually repeated throughout a song or piece in various forms. Melodies may also be described by their melodic motion or the pitches or the intervals between pitches (predominantly conjuct or disjunct or with further restrictions), pitch range, tension and release, continuity and coherence, cadence, and shape. "Many extant explanations confine us to specific stylistic models, and they are too exclusive."
