We’re on to the 7th season of Square Notes: The Sacred Music Podcast, nearing 100 episodes!
In our latest episode, we tackle the development of the Kyriale, that section of the Liber Usualis and the Graduale Romanum, which includes the chants of the Mass Ordinary: Kyrie, Gloria, Credo, Sanctus, Agnus Dei, etc. We give some specifics, as well as the cultural and ecclesiastical trends that made the groupings we now know (18 Masses, Credos, ad libitum section) possible, and touch on the impact this organization of the liturgy had on the development of the polyphonic mass.
