At 14 Mozart went to Bologna to meet one of Europe’s most famed teachers: Padre Giambattista Martini, an important scholar, theorist and composer, as well as founder of the first core of museum collections. Wolfgang spent the summer of 1770 studying with his Bologna professor, in view of the admission test to the Accademia Filarmonica (Philharmonic Academy).
Being admitted in the Accademia of Bologna was a particularly important feat for composers all over Europe and could be achieved by passing a very difficult exam consisting of writing a four-voice antiphon from the Roman gradual. Since young Mozart did not fully master the rules of counterpoint, his test was not compliant with the strict rules of the academy, so much that the intercession of Padre Martini himself was required. As he saw the genius talent of that young boy, he secretly gave him the corrected version of the test assignment.
