What does obbligato mean?
Obbligato is a specialized musical term for a part that is essential to a composition or performance. In a concerto, for example, a soloist may be given an obbligato passage rather than being allowed to improvise freely; the written part is integral to the music, not merely decorative. The word can also be used figuratively to describe a person, role, or feature that is indispensable to an undertaking. Although obbligato ultimately relates to obligation and duty, its everyday English use is most common in discussions of orchestral and chamber music. It should not be confused with optional: an optional section may be omitted, while an obbligato contributes essentially to the work's structure or character. The term is more familiar in professional music writing than in ordinary conversation.

Where does obbligato come from?
English borrowed the word from Italian obbligato, meaning “obligatory” or “bound,” a form related to obbligare, “to bind or oblige.” Italian obbligato comes through Latin obligare, from ob- and ligare, meaning “to bind.” The musical sense developed from the general idea of a part that is required rather than optional, and related English forms include obligate, obligation, and obligatory.
