Ordinary (liturgy)

The catholic mass is made of two parts: One that changes during the year, and the other one that does not. The one that does not change is usually called Ordinary. The part that canges is usually called Proper. The Latin names for these are Ordinarium and Proprium. When talkin about the music performed in Church, an ordinary usually consists of the following (which are either songs or prayers):
Kyrie eleison
Gloria 
Credo
Sanctus
Agnus dei
Protestant and Eastern Orthodox often use the same songs, but they have adapted the texts. Nowadays, the text is often translated to the local language.
