Johann Georg Zechner is considered to be one of the most prolific Austrian composers of church music during the time of Maria Theresa. His ca. 250 surviving compositions, including works in practically all genre of church music, found a wide reception in many Austrian, Bohemian and Moravian monasteries and in pilgrimage churches. His Große Orgelsolomesse was probably composed in 1761 for the dedication of the organ in the monastery at Göttweig. As in other of his late works, the strict "royal style, " which essentially characterizes Zechner's compositions, is tempered through the use of elements of the "galant" style of composition. The organ plays solistically in all of the movements.
