Through my analysis of the literature within the topic of the semiotics of music I have been able to distill common themes and approaches to self-reported interpretations of music, namely the use of scaled measurements.  For my independent variable I will use a metric developed by Tyson and McLaughlin in their RAP (rap music attitude and perception) study of male/female constructs of rap music, adjusted to my independent variables to fit within the framework of national anthems.  When put into practice of qualitative studies, the RAP scale yields high levels of consistency.  I will retain one of the variables measured in the scale, the “violent” measurement, and switch the other two to tempo and an understanding of history behind the national anthem, which will be measured through surveys. Perception of anthem data taken from surveys on three national anthems, Malaysia, The United States, and France, will be used to operationalize my independent variable.  These cases have been chosen due to the wide array of literature available for their anthems as well as the variance in the meaning of their lyrics, historical background, and tempo. Instead of
As discussed within the development of the RAP scale, analyzing potential differences between groups is an important direction to begin research to ensure validity across group lines. Original sheet music retrieved from the nationalanthem.info will be used to determine the intended tempo of the anthems, and will be operationalized into a case study of differences or similarities in the tempo and cadences of the anthems.  The same database will be used to access the original lyrics, if applicable, to the anthems of the selected cases. These lyrics will be operationalized by addressing their level of “implicit violence-” namely the mentioning of narratives of violence in the lyrics. The operationalized connection between violent tendencies and song lyrics has been studied, but I will investigate if any hidden variables exist within the realm of national anthems and cause the outcome to change due to their role as national symbols.  The indicators for my dependant variable will be the adjusted indicators from the RAP scale, changed from “views of rap music” of certain cases to an analysis of national anthems. In a similar study, Tyson found out that owning more rap media corresponds to a higher perception of rap music.  Echoing Tyson, I will assume that recognizing a national anthem by the melody for a country as well as being able to describe the historical background of the case’s anthem will indicate a positive perception of that anthem.
