This led to the development of the Very Low Profile ( VLP ) form factor DIMM with a height of ~. 72 " ( 18. 3 mm ).

* Missa Cantata ( Latin for " sung mass "): celebrated by a priest without deacon and subdeacon, and thus a form of Low Mass, but with some parts ( the three variable prayers, the Scripture readings, Preface, Pater Noster, and Ite Missa Est ) sung by the priest, and other parts ( Introit, Kyrie, Gloria, Gradual, Tract or Alleluia, Credo, Offertory Antiphon, Sanctus and Benedictus, Agnus Dei, and Communion Antiphon ) sung by the choir.
