abstract: Joseph Turrin’s compositions for trumpet are frequently performed, and have become a large part of the trumpet repertoire. His trumpet works are played at events such as International Trumpet Guild conferences, have been featured with many well-known orchestras and bands, and are standard recital works. Many of Turrin’s trumpet works have been performed and recorded by well-established musicians, which include Philip Smith, Joseph Alessi, David Hickman, Robert Sullivan, Brian Shaw, Thomas Hooten, Terry Everson, Wynton Marsalis, and Alison Balsom. This study examines in detail each of Joseph Turrin’s twenty-four published works for trumpet. Turrin’s pieces include Elegy, Caprice, Concerto for Trumpet, Intrada, Two Portraits, Someone to Watch Over Me, Chronicles, Two Gershwin Portraits, Fandango, and Three Episodes, and include pieces written for Philip Smith, Joseph Alessi, Wynton Marsalis, Harold Lieberman, Lew Soloff, Brian Shaw, Robert Sullivan, and Thomas Hooten. A complete history of each composition and arrangement, and information relating to their premieres are presented. Technical elements from the music are discussed, such as range, articulation, melodic contour, endurance, and difficult fingerings. Biographical information such as youth, education, and career about Turrin are incorporated, along with a discussion of his compositional characteristics and influences. In addition, a list of each work with an assigned difficulty grade, as well as a current discography, is included. / Dissertation/Thesis / Doctoral Dissertation Music 2019
