Dr. Gordon's professional interests lie in the areas of theory pedagogy, the use of technology in the classroom, and in the perception and cognition of music. His dissertation - "Harmonic Progression to the Dominant: An Experiment in Aural Perception" - explored the nature of trained musicians' recognition of and preferences for pre-dominant harmonies. He has been selected by the Educational Testing Service/College Board as a reader for the Advanced Placement Music Theory examination. Dr. Gordon regularly presents clinics and workshops on computer applications in music, and has trained hundreds of professionals in the use of technology in the music classroom. His interest in music software led to his work for Alfred Publications in the development of Essentials of Music Theory, and with Sibelius in the production of Sibelius 4. He often serves as an adjudicator at band events and has conducted honor bands across the southeastern United States. He is active as a freelance trombonist and has performed with the Asheville, NC Symphony Orchestra, the Brevard, NC Chamber Orchestra, the Smoky Mountain Brass Band, the Appalachian Brass Quintet, and the Roman Festival Brass.
