Something that is essential or necessary and cannot be left out.
In the performance, the obbligato part was crucial to the overall sound of the music.
A musical term referring to an important accompaniment that enhances a main melody, often played by a single instrument.
The violin played an obbligato that beautifully complemented the singer's voice.
Obbligato is derived from the Italian word 'obbligato', which comes from the Latin 'obligatus' (meaning bound or obliged), from 'ob-' (meaning to, towards) and 'ligare' (meaning to bind). The term originally referred to a musical part that is essential or binding in a composition.
Think of being 'bound' ('ligare') to something 'towards' ('ob-') — that's why obbligato means a necessary part in music.
