During services of the Reformed Churches of South Africa (RCSA), certain psalms and Biblical hymns are used frequently, while others are almost never used. The objective of this study is to determine how the Psalter of 2003 can be used optimally. The model of Zerfass is used for the investigation. The final results of the study are presented in the form of a model that can enrich the optimal use of the Psalter 2003 as means of communication in the liturgy of the RCSA. In Chapters 2 and 3, a basic-theoretical investigation is conducted, with reference to perspectives from Scripture and history. The investigation reveals that music and songs had already played an important role in the church of the Old Testament, and that the Psalms had had a significant influence on the liturgy and the faith. In the New Testament, new hymns are found that supplement those from the Old Testament. The form in which these hymns were composed, was closely connected to the context whence these songs arose. The communication that a hymn effects, is achieved jointly by word and music, in the church of the New Testament and subsequently. Since the Reformation, a degree of separation arose between the songs used in the church and outside, but mutual influences are observed. In Chapters 4 and 5, attention is paid to metatheoretical perspectives, first in communication science, then in hymnology. It is in their singing that the congregation participates in the worship of a church service. Such singing is indeed the basic form of participation, which promotes communication among members of the congregation. In judging a metrical version of a Psalm, attention should especially be paid to the content, style of the text and the melody. In the empirical investigation, qualitative and quantitative methods are used. The investigation proceeds in three phases. In the first phase, information is obtained about the hymns that were sung in a number of congregations in the course of a year. In the second phase, a questionnaire was set and sent to ministers, organists and members of congregations. In the final phase, interviews were conducted with ministers and organists from five congregations. The data show that the hymn occupies an important place in the liturgy. However, the investigation reveals that this point of departure is not fully realised in practice, and some shortcomings are identified. In particular, there is a need for extension of the hymnody, especially by hymns from the New Testament. In Chapter 7, an indication is given of the factors that constrain the optimal use of the Psalter 2003 as means of worship in the church service. The most important problems are: • the incomplete utilisation of the full collection of hymns in the Psalter, • the underuse of the 2001 metrical version, • the repeated use of a small subset of hymns, • problems with the melodies and liturgical usefulness, • limitations in the training of ministers and organists, • resistance to the 2001 metrical version, • a lack of proper programmes to practice the new hymns, and • inadequate support and encouragement by church councils in respect of improving the skills of organists. In view of these problems, a model is proposed, which identifies the relationships among the role players / elements necessary to promote worshipping through singing: • the users of the Psalter 2001, viz. Ministers, organists and members of the congregations, together with the role of the church council, • the Psalter 2003 as hymn book, and • the possible extension of the current corpus of hymns. / Thesis (Ph.D. (Liturgics))--North-West University, Potchefstroom Campus, 2009.
