matins and lauds of Good Friday and Holy Saturday could no longer be anticipated on the preceding evening, and even matins and lauds of Holy Thursday was allowed to be anticipated only in the case of cathedral churches in which the Chrism Mass was held on Holy Thursday morning. The 1960 Code of Rubrics, which was incorporated in the next typical edition of the Roman Breviary, published on 5 April 1961, a year ahead of the publication of the 1962 edition of the Roman Missal, allowed no anticipation whatever of lauds, though matins alone could still be anticipated to the day before, later than the hour of vespers. In sum: Until 1955 the three consecutive Tenebrae services for Holy Thursday, Good Friday and Holy Saturday, including the typical ceremonies such as the extinguishing of candles, with each of these three services anticipated on the previous evening, were widely celebrated as an integral part of the liturgy of Holy Week in churches with a sufficient number of clergy wherever the Roman Rite was followed. A rich tradition of music composed for these central occasions had developed. From 1956 to 1970 the practice largely declined: The 1955 papal document restored the celebration of matins and lauds of Holy Thursday, Good Friday and Holy Saturday to their original timing as morning services, with only a little allowance for anticipating any of them on the evening before. On these three days attention shifted from what became morning services to the services that were now to be held in the afternoon or evening. Communal celebration of matins and lauds became limited generally to communities that observed the full Divine Office in congregational form. Matins and lauds, having lost their exceptional character, provided composers with little incentive to produce new music for them and there was no demand for grand performances of the existing music earlier composed for Tenebrae. The Roman Breviary, as updated in 1961, did not mention any specific Tenebrae ceremonies to accompany the no longer anticipated matins and lauds of Maundy Thursday, Good Friday and Holy Saturday. Finally, in the wake of the Second Vatican Council, matins and lauds throughout the year were completely reformed. Matins, for instance, no longer had the nine psalms and lauds the five psalms that determined the number of candles extinguished in the Tenebrae celebration.
