This study aims to two problematic aspects of the Phrygian mode: a. the development of a harmonic pattern at the cadence that differs from that of the other modes and of the major and minor modes as well; b. the observation that the Phrygian scale inverts all of the intervallic properties of the Major scale. The result of these two observations is that when the reductive techniques of Heinrich Schenker are applied in the Phrygian repertory, melodic and harmonic properties are brought into conflict with each other. However, application of alternative models of the Ursatz developed by Lori Burns has certain benefits for demonstrating musical properties in the Phrygian repertory.

The aim of this study is to identify the main differences in compositional style in selected chamber music works by Hendrik Hofmeyr (Sonata per Flauto e Pianoforte, Sonata per Clarinetto e Pianoforte and Sonata per Violoncello e Pianoforte) and Alexander Johnson (Imicabango for flute and piano, Three Incantations for flute, clarinet and piano, and Khalagari for flute and piano). After a thorough analysis of the melodic-, harmonic-, rhythmic-, and structural elements, it was clear that the two composers’ composition style is different from one another. Differences can be identified under the following main points: form structure, melodic and harmonic content, recurring motives and texture. Hofmeyr makes use of traditional form structures, such as sonata form, ternary form, and theme and variations. Johnson does not use traditional form structures and makes use of free form structures, such as: A1-A2-A3-A4-A5- A6-A7 (second movement from Khalagari), ABABC (third movement from Three Incantations), and A1-A2-B-A3-closing section (first movement from Three Incantations). The first movement from Khalagari is the only movement where references to sonata form can be found. Hofmeyr uses existing modes and scales in his works. Both his Sonata per Flauto e Pianoforte and Sonata per Violoncello e Pianoforte contain numerous examples where he makes use of the octatonic scale and the phrygian mode. Examples of the hexatonic scale can be found in the first and second movements of the Sonata per Clarinetto e Pianoforte. Hofmeyr’s chord structures are also based on these scales and modes. Alexander Johnson does not use any of the above-mentioned scales, but rather makes use of his own scale (labeled as the “Johnson-scale” in this study). His chord structures are also based on this scale. Hofmeyr does not use themes and motives from other compositions in the three works in this study. He does however combine themes from earlier movements within a composition. Examples of this can be found in the third movements from Sonata per Flauto e Pianoforte and Sonata per Clarinetto e Pianoforte. Johnson combines motives and themes from other compositions in his works. Motives from Three Incantations can be found in Khalagari. A detailed summary can be found in the conclusion of this study. / Thesis (DMus)--University of Pretoria, 2014. / tm2015 / Music / DMus / Unrestricted
