“These tropes added to liturgical texts ad libitum were contained in special books,”
The Catholic Encyclopedia, Volume 6: Fathers of the Church-Gregory XI
“+ The intonations or chants ad libitum, Asperges me, Gloria in excelsis, and the more solemn tones of the Prefaces must not be placed in the body of the Missal, but only at the end, in the forms of a supplement or appendix; to them (the ad libitum intonations or chants) may be added, either in the Missals or in separate publications of the chanted parts, the chants of the "Toni communes", already published in the "Gradual", which have reference to the sacred ministers.”
