Patronage
2 saints are venerated as patrons of sacred music, led by Sixtus I (feast day April 6).
42 — 126 · Feast day: April 6
The seventh Pope, Sixtus I governed the Church in Rome from c. 117 to c. 126 during the reign of Emperor Hadrian. According to the Liber Pontificalis, he decreed that only sacred ministers may handle the sacred vessels, and that the congregation shall recite the Sanctus with the priest after the Preface — early steps in formalizing the Roman liturgy.
635 — 685 · Feast day: May 7
A Roman-born pope who trained in the schola cantorum and was known for his knowledge of Scripture and his care for the poor. Elected in 683, he waited nearly a year for Byzantine imperial approval before his consecration. He then secured a decree from Emperor Constantine IV delegating papal confirmation to the Exarch of Ravenna, shortened future interregna, and restored several Roman churches.
