Joseph Turrin (b.1947) is a composer, orchestrator, conductor, pianist, and teacher whose wide-ranging activities have contributed greatly to many aspects of contemporary American musical life. His numerous ASCAP awards (1981-20050, as well as his many other awards, document his professional success. His many commissions by various orchestras around the world, bands, brass ensembles, soloists, theatre groups and film scores show his popularity. He is also in high demand as a pianist for orchestras, in theatre productions, in commercials and studio recordings as well as serving as personal accompanist for Jerome Hines, Phil Smith, Joseph Alessi and others. Mr. Turrin's compositions for trumpet and piano have been particularly popular among college and professional players as seen by their frequent performance in those venues as evidenced by the International Trumpet Guild's Trumpet and Brass Programs for the years 1995-2002. The three works selected for the present study include: Elegy for Trumpet and String Orchestra (1971, rev. 1993, piano reduction, 1993), Caprice for Trumpet and Piano (1972), and Intrada for Trumpet and Piano (1988). In this in-depth study, special attention is given to those characteristics which create unity of form, and those traits that seem to be idiomatic of Mr. Turrin's style of writing. A comparison of the three pieces allows for the extrapolation of common style traits, which include certain traditional fanfare-style motifs as well as jazz-style elements. Conclusions are drawn with detailed explanation of what I consider the appropriate application of the knowledge from the analyses to quality performances of the pieces studied. Careful instruction is given concerning the various aspects of performance style which are supported by the study done on each piece. Finally, an interview by internet with the composer answers some of the questions created by the analyses. Several of the composer's comments justify many of the conclusions drawn by this study.

Hemispheres is a three-movement work for winds written by Joseph Turrin in May 2002. Commissioned by Kurt Masur for the New York Philharmonic, he wished to include a piece exclusively for winds and percussion in the programming of his farewell concert that commemorated his eleven years as Music Director. The work is in three movements: Genesis, Earth Canto, and Rajas which represent three different cultural views of creation. Formally, this work is based structurally and thematically on melody rather than harmony. This analysis focuses on three main tools which unify this work. The first is that thematic material from the first movement is reintroduced and developed in the second and third movements. The second is a consistently reoccurring rhythmic grouping in threes. This three note motive, found in all three movements, is used both melodically and as an accompaniment. The third is the unifying pitch center of C. Through an economy of musical means, Turrin composed Hemispheres with only a minimal number of themes and motives, each developed through the course of all three movements.

This study addresses on facet of Joseph Turrin's compositional oeuvre: his published works for solo trumpet. Complete histories if all six trumpet compositions are chronicles. A discussion of formal organization and significant style features including harmonic language, melodic style and rhythmic features is included. A detailed performance analysis follows. The degree of difficulty of each work is assessed through an investigation of tessitura, range, melodic contour, endurance factors, fingerings, and technical features of the accompaniment. Analysis of tempi and dynamics, articulation and phrasing, and timbral considerations provides additional points of focus to the study. Finally, the importance of Turrin's works for trumpet and his impact on trumpet literature is assessed. Idiomatic aspects of composition that make Turrin's music attractive to performers are investigated and discussed.
