In quick succession he was steward, chancellor, prior, abbot, for a time, parish priest at Türnitz, and brought the monastery to prosperity.
In 1827 he was founded a string quartet in Eger by his noble music instruments, one of these the 1697's Stradivari's violin, named Cecilia, newly discovered in 2011.
His first dramatic work, "Historische Schauspiele", appeared in 1810, and contained three five-act tragedies: "Die Corvinen", "Karl der Kleine, König von Ungarn", and "Zrinis Tod".
The "Tunisias", an epic in twelve cantos, describing the conquest of Tunis by Emperor Charles V, appeared in 1820, and there have been frequent later editions.
As a lyric poet Pyrker published only a few monographs, e. g. "Lilienfelds Freude", and "Lieder der Sehnsucht nach den Alpen" (1845).
