Obbligato

The term obbligato (Italian, from Latin obligatus: " set binding " ) in classical music means that the designated voice must not be omitted, as opposed to score - specified ad libitum.

The roots of this statement in Baroque music, where in contrast to a writing elaborate obbligato voice the accompanying continuo voices were not usually written in full. A concertante voice was unlike these ripieno voices as Violino designated as mandatory. Also a detailed elaborate accompaniment could be in contrast to the outlined basso designated mandatory ( obbligato accompaniment to ).

Contrast, was mostly written out every vote in scores from the 19th century, so the use of this additive was rare. The provision of an instrument with the addition of mandatory still means that this must not be omitted, as the violin obligate in the salon music.

In music treatises of the 16th and the 17th century was mandatory based on ostinato votes of the figured bass.

Jazz

In jazz can mean mandatory for vocals also improvising accompaniment. The term is first jazz mainly used in New Orleans in terms of improvisation of the clarinet, which plays the melody voice playing cornet. But in other jazz forms the obbligato may occur. For example, in the interaction of Billie Holiday and Lester Young, Gerry Mulligan and Paul Desmond.
