Like the [[Serpent (instrument)|serpent]], another fingerhole horn that was paired with it, the cornett was used to reinforce the human voice, accompanying choral music. The cornett was deemed to be similar to the voice of a [[boy soprano]], a part found in English liturgical music which the cornett accompanied.<ref name=Groveonlinecornett/> Not only English, for [[Mersenne]] speaks of the cornett being "heard with the choir voices in the cathedrals or chapels."<ref name=Groveonlinecornett/>

Historically, two cornetts were frequently used in consort with three [[sackbut]]s, often to double a church choir, into the 18th century.<ref name=Groveonlinecornett/> This was particularly popular in [[Venice|Venetian]] churches such as the [[San Marco di Venezia|Basilica San Marco]], where extensive instrumental accompaniment was encouraged, particularly in use with [[antiphonal]] choirs.
