Born in Massa in December 1728 into a family having a rich musical heritage, PIETRO ALESSANDRO GUGLIELMI received his earliest education from his father and his uncle who started him in counterpoint, viola and keyboard. Later, thanks to the protection offered by the Duchess Ricciarda Gonzaga of Massa, he was admitted to the S. Maria of Loreto Conservatory of Naples into Francesco Durantes’s class which he probably attended until 1754. It was still in Naples where he made his debut in the comic opera genre (“Lo solachianello imbroglione”, 1757), but his first serious opera, “Tito Manlio” was staged in Rome in 1763. After years of intense activity in Florence, Padua, Turin and Venice in 1767 he moved to England where he was appointed composer for and musical director of the King’s Theatre where he stayed until 1772, notwithstanding the open hostilities of his colleagues due in large part to the success he obtained for his numerous works. His return to Italy was marked by other moves, not least those involving the cities of Naples and Rome, the latter giving him the possibility of taking over Antonio Borroni’s place as kappelmeister of S. Peter’s under Pio Vl’s papal rule, and, in 1797 the same position at S. Lorenzo in Lucina. As a writer of opera Guglielmi enjoyed great fame during his life, to such a point that he was considered on a par with his contemporaries Cimarosa and Paisello, concrete proof of his acclaim notable in the commissions he received from the Neapolitan court for official occasions. Even if he did not disdain the normal composing practice of outlining the principal lines leaving his pupils to complete the work, a common enough modus operandi in that period, Pietro appears as a whole, as a composer of international tastes and in no wise a conservative. The serious operas reveal a greater number of ensemble pieces, especially duets and trios, which in the period following the 1760's mostly exploit the “explicit” in the first and second acts, focal points of the drama thanks to the use of a unifying construction that conducts the listener to the apogee. The employment of a varied “da capo” form contributes to this effect. The later compositions from the 90’s on tend to be given over to two-act works having a simplified structure and experiment with a greater ease of passage between the recitatives and arias. Similar developments can be traced also in the comic repertoire after 1770 where the climax of the plot is reached in the last scenes of an act where an ever-increasing number of participants tends to compress the action. The “da capo” aria is gradually replaced with other more varied and flexible models adapted to the exigencies of the texts. His sacred music, largely unknown, is marked by the innate ability of the counterpoint writing and for his tendency to use structures for effect in the same manner as his operas, above all in the final sections. They are mature works dating from the later years of his career when he was employed as the kappelmeister at Rome. In the catalogue of his chamber music works his pieces for harpsichord are to be recommended. Structured generally in two movements (a fast tempo movement followed by a minuet or a rondo) they retain their interest notwithstanding their repetitiveness by the way the composer plays with the sound and mechanical possibilities that the instrument offers, sometimes including dynamic solutions that will be further developed at a later date by composers for the pianoforte.
