With his Te Deum (1677), Lully produced a singularly important work, which was to impose an "official" genre which lasted a century: a chef-d'oeuvre of musical architecture, the imposing forces require trumpets and timpani and was the religious work the most often performed at that time. Another substantial work the Missa Salisburgensis by Biber is of an exceptional ostentation. The music, is written for fifty-three different voices, which have to be divided up in the space into two choirs. The impressive forces of trumpets and percussion, indicate the solemnity of the ceremony and thereby resonate splendidly, responding to the angelic choirs like divine acclamations, in order to build a musical monument which would be talked about for eternity.
