style of church music. After 1773, the examination became more severe,[47] and an Italian who stood the test at the beginning of this century, speaks of it as consisting of three separate compositions. First, the given subject was to be arranged for four voices in _falsobordone_, i.e., in plain harmonics, after the fashion of our congregational chorales. The second test consisted of a _disposizione di parte_. One voice retained the Cantus firmus, the others were to be set to it in canonic or imitative mode. The motifs were often taken from the Cantus firmus itself, in a rhythmical, diminished form. Strict imitation was not enjoined; it sufficed that the voices should follow each other with similar passages. The third task was a _fuga reale_, a perfect fugue, according to the rules of the church mode of the Cantus firmus, in which one phrase is carried through as a theme, the other parts serving as intermediate phrases. Wolfgang did not go through this examination without preparation. An elaboration in his boyish handwriting of the Cantus firmus "Cibavit eos in adipe" (44 K.) is probably an exercise made under Padre Martini's directions. His trial work was a Cantus firmus from the Roman Antiphonary, a freely imitative contrapuntal arrangement of the accompanying parts overlying the Cantus firmus of the bass, which is only to be adhered to in its melodic progressions, and may be modified in its rhythmical divisions. The original from Mozart's hand is in the archives of the Philharmonic Society, where it was found by Gaspari in a volume of various test works chiefly by Martini's pupils.[48] Next to it among the documents was a second elaboration written by Padre Martini, and copied by Wolfgang. Of this a second copy is in the Mozarteum, from Wolfgang's hand, with his father's subscription: _Dal Sigr. Cavaliere Amadeo Wolfgango Mozart di Salisburgo, Scritto nella sala dell' accademia filarmonica in Bologna li 10 d' Ottobre, 1770_. This was published as Wolfgang's own test work (86 K.).[49] Probably Padre Martini went {MILAN--"MITRIDATE."} (129) through the boy's work, which was not free from faults, and was entered in the protocol as "satisfying the conditions," and showed him how the task might have been executed; he took the copy of the corrected exercise to Salzburg when he returned there.
