taverner composed eight masses. the most famous one is called the "western wynde". it was a “parody mass”, which meant that it used a popular tune with that title. another mass was called "gloria tibi trinitas". this work set a fashion for pieces which were called "in nomine"s, because the tune was from the benedictus in the mass which sets the words “in nomine domine” (“in the name of the father”). “in nomine”s were compositions for instruments which used this tune.
