For applied teachers of the bel canto method of singing, classical musical theatre repertoire provides an abundant resource of material for teaching the undergraduate baritone voice. Select classic musical theatre repertoire, fitting within the parameters of suitable range, tessitura, duration, and thematic material for an undergraduate baritone, will be used to demonstrate the application of bel canto techniques such as: glottal onsets, the connection between the speaking voice and singing voice, suitable vowels in building the upper range, and teaching sostenuto and legato. This dissertation serves as a guide for teaching sound vocalism through classic musical theatre repertoire.

Latin American art song is a genre primarily of the first half of the twentieth-century, when popular folklore served as the voice and inspiration of many poets and musicians. The nationalist movement served as a means of expression, each Latin American country with its own identity. There is great benefit for singers to study Spanish diction at an academic level, since it is a language already familiar to most U.S.A residents. There is a significant amount of unknown repertoire that would be very useful in the singing studio because of the language's open vowels. This repertoire can also serve as a confidence-builder to young Spanish-speaking singers at the beginning of their training. I will be focusing on the (s), (ll), and (y) sounds as pronounced in the diverse regions of Latin America; in particular, why they matter when coaching singers, and the articulators involved in each. The purpose of this study is to discuss diction differences in the repertoire, expound on its benefits for voice pedagogy, all while informing about varied options for recital programming.

For most of the twentieth century, opera singers were not beholden to the ideal physical standard of women dictated by popular culture, but rather focused on serving the music and perfecting their artistry. Unprecedented sociocultural changes throughout the twentieth century exposed the shifting ideals of each generation and how they were promoted through mass media and advertising. This thesis surveys the time period of the 1890s to the present day for the purpose of analyzing cultural trends, philosophies and technologies that shaped the century. Societal pressure to make the body a project and the focus of one's own intense attention now reflects back onto the opera stage where audience members expect to see what society has dictated to be an acceptable female form. Artistic and stage directors are influenced by society's decree that only thin is beautiful, imbedding into the mindset of the art form notions that now affect how female professional opera singers are depicted and even employed.
