ABSTRACT
In his autobiographical sketch Joseph Haydn claims to have learned the 'true fundamentals of composition' from Nicola Porpora. Porpora (1686–1768) was a student of Gaetano Greco at the Conservatorio dei Poveri in Naples and later himself became a maestro at the Conservatorio di San Onofrio, where Francesco Durante also taught, That Haydn's teacher Porpora came from the centre of the partimento tradition, which has attracted increased scrutiny by music theorists in recent years, justifies examining Haydn's relationship with this long-standing pedagogical method and compositional practice. In this essay I analyse the sources that shed light on Porpora's relationship to the partimento tradition and on Haydn's relationship to Porpora. Focusing on partimento counterpoint, I examine several of Haydn's fugues in contrasting genres in order to illustrate how the principles of thoroughbass and partimento help to explain particular structural procedures in Haydn's music, as well as the compositional processes that produced them.
