James Wintle's, Northwest Miniatures for flute, trumpet and piano is a unique work in the chamber music repertoire. In addition, the use of auxiliary instruments makes this piece a rarity in the flute and trumpet chamber music repertoire. There are a limited number of resources presently available to performers regarding Northwest Miniatures.This dissertation provides a pedagogical performance guide addressing the inherent challenges for the flutist and this instrumentation and serves as a new resource for performers and scholars of this work. It provides a performance analysis of the piece along with pertinent pedagogical information and exercises to assist the flutist. Insight from the composer on how to address these challenges is also included. Because there are a limited number of scholarly resources available on the subject of flute and trumpet chamber music, this dissertation is a significant contribution to this genre of repertoire.

James Wintle (b.1942) is one of America's most successful living composers. Wintle and his compositions have attracted the attention of many prominent performers and scholars over the last three decades. The Key for trumpet and piano was composed in 1988 for Chris Gekker, an outstanding trumpet player. The Key consists of four movements: a fast movement in free form, a slow lyrical movement in song form (ABA'), a dance-like movement influenced by ragtime, and a fourth movement with a slow introduction in rondo form (ABA'CA''). The purpose of the study is to introduce the composer, James Wintle, and to present an analysis of The Key for trumpet and piano, a work which receives frequent performance. Through research and analytical approaches, the study focuses on a theoretical analysis of The Key for trumpet and piano. In addition to using available materials and resources, the author was in direct contact with James Wintle for the study. Chapter 1 presents the purpose of the study, the state of research, and method. Chapter 2 is devoted to James Wintle's biography. Chapter 3 examines Wintle's compositional style, including influences and musical language. Chapter 4 offers a theoretical analysis of all four movements of The Key, as well as a discussion of extra-musical influences from the painting entitled The Key by Jackson Pollock. A summation and conclusion follow in chapter 5.

The purpose of this dissertation is to analyze the ways in which distinguished American composer James RayWintle (1942-2013) addresses the problem of formal unity and incorporates previous musical styles in his post-tonal compositions. Because post-tonal music lacks many of the pillars that create tonal structure, it can be difficult for a composer to maintain a sense of form when writing in this style. Wintle attempts to circumvent this issue by incorporating common-practice elements, such as formal sections, familiar stylistic gestures, and referential-pitch organization into his works. For this analysis, the author has selected three of Wintle’s piano compositions that best represent his compositional approach and diverse techniques: Album Leaves - A Set of Five Character Pieces for Piano (2001), Scherzino (Street Scenes of Ovada) for Solo Piano (2010), and Four Miniatures for Piano Four Hands (2003). Wintle’s artistic style borrows extensively from Western classical music, encompassing various historical periods and quoting several major composers. Additionally, he incorporates a variety of musical styles into his chamber works and those for solo piano. These range from the dance suites of the French Baroque and Brahmsian-character pieces to American ragtime. This research also describes Wintle’s compositional style and his borrowing of 18th- and 19th-century techniques, forms, and titles, all set in a post-tonal language. The interviews conducted with the composer and his own program notes serve as primary sources, lending an invaluable insight into his works.
