Definition

1. Noun:
   • An essential musical part: In music, an "obbligato" refers to a prominent, independent instrumental part that is considered essential to a composition and must be performed as written, without omission or significant alteration. It is not merely an accompaniment but a vital, often soloistic, line.
   • A persistent subordinate motif: It can also describe a recurring, distinctive musical figure or motif that plays a supporting yet integral role within a piece.

Examples of Usage

  • The violin obbligato in the aria was beautifully performed. (The essential violin part in the aria was beautifully performed.)
  • The composer wrote a flute obbligato to accompany the vocal line. (The composer wrote an essential flute part to accompany the vocal line.)

Advanced Usage
