The Jargon of Music

In Thomas Regelski's (1996) article, "Musicians, Teachers, and The Social Construction of Reality," he talks about how problematic "specialized" or "institutional language" can be because "it is used as much to keep others out as it is to facilitate communication for insiders" (p. 99). However, I found it interesting that throughout his article, Regelski continually uses plenty of philosophical jargon, thereby excluding much of the population. In almost every paragraph, there was a new word in italics. Later on he writes, "While the paradigm of using foreign words [in music] may have certain advantages for communication in an increasingly international music world, students do not have to be taught jargon in order to induce musical learning" (p. 99). So, what is the purpose of using the italicized philosophical jargon?
