This thesis sets out to investigate new notation symbols, systems, and string techniques in some one hundred 20th century string quartets, selected from a variety of composers. The analysis includes compositions that have, through contemporary aesthetic ideals, extended musical and technical resources and stimulated the development of compositional methods in such a way as to influence later works in the genre. k The thesis divided into two parts : Histoiy and Research Part One is a brief history of 20th century music, and includes the development o f the string quartet from earliest times up to the mid-century. Part Two researches string techniques and notation from the turn of the century up to 1990. The historical perspective demonstrates that after World War n, with the emergence o f the electronic age and a changing social and intellectual climate, traditional concepts were being challenged. Composers facing the dilemma affecting music in general, and the string quartet in particular, had to adapt to radically developing techniques and styles. Sounds and syntax o f a different type were initially, but unsuccessfully, sought to unify the divergent thinking o f the time. Ultimately, the developmental paths took shape from the problem itself and different approaches emerged to master the multi-faceted dimensions available to composers. Part Two investigates music syntax from the viewpoint of recording new symbols, notation systems and string techniques. Quartets of the first half of the century show that both the dissolution and the extension o f traditional processes were contained, importantly, within the continued use of conventional notation. The impact and significance of these quartets within the context of 20th century development cannot be ignored. However, the quartets researched post-1960 demonstrate that composers have enlarged all parameters of the genre through the extension of traditional resources and by radical innovation. This research demonstrates that the emergence of new symbols and string techniques in the second half of the century has been largely on an arbitrary basis. Nevertheless^ broad classification of these elements is undertaken. / Art History, Visual Arts & Musicology / D.Mus. (Musicology)
