Violoncello Contrabass and Bassoon-We know that Mozart held his Vespers in high regard since he once asked his father in a letter dated 12 March 1783 to send the two works to him in Vienna so that he could show them to Baron Gottfried van Swieten. The Office hymns designated as Vesperae de Dominica K. 321 and Vesperae solennes de Confessore K. 339 both call for four vocal parts two violins two clarini kettledrums basses (violoncello double bass and bassoon) three trombones and organ.They contain settings of Psalms 109 (Dixit) 110 (Confitebor) 111 (Beatus vir) 112 (Laudate pueri) 116 (Laudate Dominum) and of the Magnificat canticle. Each of the Psalms forms an autonomous unit; the Doxology atthe end is derived from the themes of the various Psalms.Urtext of the New Mozart Edition Full score & performance material (BA4893) vocal score (BA4893-90) available for sale
