Low Mass (in Latin, Missa lecta) is a Tridentine Mass defined officially as Mass in which the priest does not chant the parts that the rubrics assign to him. The view expressed by Adrian Fortescue in 1910, that Missa Cantata "is really a low Mass", has thus been officially rejected, and "the rubrics of the Low Mass do not permit the priest to chant", though singing by others may accompany his celebration of Mass.
