This research has shown that choice of repertoire is a major determinant of a choir's success. The ability to select good repertoire has been identified as one of the most important skills required of a conductor. The study further describes the selection processes applied by conductors and establishes which factors influence their choices. The effect of the personal background and life history of the conductor on the choice of repertoire was determined. These aspects include the following: the influence of role models, membership of choirs, tertiary education and non-musical influence. In addition, the research focused on the influence of performance opportunities, participation in choir competitions, exposure to local and international children's choirs and the availability of funds. Various roles, such as those of the conductor, choir members, management bodies, choir members' parents and accompanists were examined concerning the choice of repertoire. The study indicates how conductors adjust their repertoire choices during their terms as choir directors. Important criteria in regard to children's choir music were established, sources used were identified and the inclusion of South African compositions was determined. Perceptions regarding choir arrangements and folk music as repertoire were gauged. The respondents were predominantly South African conductors of children’s choirs. Although the perspective is largely South African, seven foreign respondents were involved, thus incorporating the opinions of internationally recognised conductors of children's choirs. Even though both the South African and the foreign participants represent a sample that cannot be regarded as representative of the South African or other population groups, the researcher collected valuable data which generated insightful conclusions about the selection of repertoire by local and foreign conductors. Much insight was gained into social and political circumstances in South Africa and into the cultural diversity of South African choirs that offer South African conductors of children's choirs unique opportunities and challenges regarding their choice of choir repertoire. In addition to conductors as respondents, the researcher included South African composers of children's choir repertoire. These composers contributed significantly in respect of the origin of their interest in children's choir compositions, as well as decisions concerning the choice of text. Furthermore their view on the role of religion, preferences regarding a cappella or accompanied works, the use of experimental techniques, general criteria for children's choir repertoire and their opinions on the development of the South African children's choir movement over the past decade, were considered. The research includes an analysis of children's choir concert programmes from 1968 – 2004. Trends in concert programmes over a thirty-six year period were documented. The conclusion was reached that children's choirs have, since the twentieth century, had the same status worldwide as that of any other ensemble. Therefore the demands regarding the selection of repertoire and performance standards are high. Choice of repertoire is closely linked to unique considerations by the conductor, as well as to local and international trends that influence this choice. Successful repertoire choices play a vital role in successful choir performances.
