Those undertaking the study of a musical instrument may focus on a specific genre of music or diversify through exploration of a range of styles and forms. Students wishing to gain insight into a variety of styles may seek guidance from a number of sources, particularly in their formative years. In the interests of achieving stylistic authenticity and in the absence of teachers with wide-ranging musical experience, the student may seek direction from repertoire and pedagogical resources. This research aims to address a deficiency in existing repertoire and teaching materials for the beginner to intermediate classical clarinet player by contributing to and extending current resources. The thesis is presented in two parts - folio (60%) and exegesis (40%): The folio involves the creation of a series of original works written in a range of archetypal jazz, popular and classical music styles, aimed at providing a level of instructional support for both student and teacher in the achievement of stylistic integrity. This is realised through the inclusion of annotations and recommended practice strategies for each piece, as well as a general guide to style section. To be of further educational value to the student, compositions in the folio incorporate both traditional and extended techniques. The exegesis reviews current leading instructional manuals and repertoire, discusses their strengths and weaknesses and identifies areas where resources are deficient. It analyses and presents an overview of compositions in the folio and provides a detailed commentary of the compositional process, using a selected work as an exemplar. Given the nature of the folio, which is aimed at the young clarinet player and teacher and commences with advice on style followed by a series of compositions, the exegesis precedes the folio in this thesis.
