Antiphons and Other Parts which Help in Praying the Psalms (paras 110–120). Moreover, there is no consistency in the terminology. A term oratio psalmica – psalm-prayer – appears together with a more meaningful term oratio super psalmum, which could be translated literally as a prayer on a psalm. A particular aim of such a prayer is stated: the psalm-prayer sums up the aspirations and emotions of those saying them (oratio psallentium affectus colligat et concludat – para 112 ). These prayers should be provided by a Supplement to the book of the Liturgy of the Hours as the Instruction claims. Such a supplement has never appeared. Liber Orationum Psalmographus Pinell's work on the reform of the liturgy Although it is difficult to explain the Supplement absence, it is possible to find how its announcement was included in the Instruction. According to the reports of the several post-conciliar commissions working on liturgy reform, Jorge Pinell OSB (1921–1997) gave a particular impulse to introduce psalm-prayers to the renewed Liturgy of the Hours. He was a Spanish monk of the Abbey Santa Maria de Montserrat belonging to the Benedictine Subiaco Congregation. Pinell studied at Catholic University of Leuven, Pontifical Gregorian University and Pontificio Ateneo Sant Anselmo in Rome and became a professor of liturgical studies at the latter. Staying there he actively took part in works on liturgy reform after the Second Vatican Council as a scholar and a member, so-called consultor, of the Consilium ad Exsequendam Constitutionem de Sacra Liturgia – Commission for implementing the Constitution on the Sacred Liturgy Sacrosanctum Concilium promulgated in 1963. Members of the commission knew about Pinell's work on the critical edition of psalm-prayers and were waiting for the final draft. Although Pinell considered only the psalm-prayers of the Mozarabic or Old Spanish Rite, there was a reason to use them in the reform of the Roman Rite. The aim of the reform was to reshape highly monasticised heavy Roman Rite to its original light cathedral form. The lack of sources from such a primitive stage of the Roman Rite development made this task impossible, at least directly. Commission members decided to include cathedral elements of other Latin rites. Such cathedral elements taken from the Spanish Rite were psalm-prayers. Psalm-prayers' role in the renewed Liturgy of the Hours would be to ease recitations. Others did not want to include psalm-prayers to the main text of the Liturgy
