Modern Forms of an Ancient Art: A Selection of Contemporary Fanfares for Multiple Trumpets Demonstrating Evolutionary Processes in the Fanfare Form

Description: The pieces discussed throughout this dissertation provide evidence of the evolution of the fanfare and the ability of the fanfare, as a form, to accept modern compositional techniques. While Britten’s Fanfare for St. Edmundsbury maintains the harmonic series, it does so by choice rather than by the necessity in earlier music played by the baroque trumpet. Stravinsky’s Fanfare from Agon applies set theory, modal harmonies, and open chords to blend modern techniques with medieval sounds. Satie’s … more

Near-Death and Out-of-Body Experiences in a Melanesian Society

Description: Abstract: "The texts of three near-death experiences, one vision, and one dream by Melanesian villagers are presented and analyzed with regard to their cultural context. Comparison of these experiences with those reported from North America and India suggests that while they have common features (such as the appearance of apparitions, and visions of paradise), their interpretation is structured by cultural expectations."
