A solemn mass, its name ("in honour of the Most Holy Trinity") and date indicate that it was likely to have been composed for Trinity Sunday, for use in Salzburg's Dreifaltigkeitskirche (de) (Trinity Church). This is Mozart's only wholly choral mass setting, excluding all solo vocalists. Einstein contends that this may have been done in order to achieve brevity, following the directive of Archbishop Colloredo.
