Description
The study of acoustic ecology is concerned with the manner in which life interacts with its environment as mediated through sound. As such, a central focus is that of the soundscape: the acoustic environment as perceived by a listener. This dissertation examines the application of several computational tools in the realms of digital signal processing, multimedia information retrieval, and computer music synthesis to the analysis of the soundscape. Namely, these tools include a) an open source software library, Sirens, which can be used for the segmentation of long environmental field recordings into individual sonic events and compare these events in terms of acoustic content, b) a graph-based retrieval system that can use these measures of acoustic similarity and measures of semantic similarity using the lexical database WordNet to perform both text-based retrieval and automatic annotation of environmental sounds, and c) new techniques for the dynamic, realtime parametric morphing of multiple field recordings, informed by the geographic paths along which they were recorded.

Description
The trained singer utilizes an awareness of her body as an instrument. When she becomes pregnant, her body changes in numerous ways to support the pregnancy. Many of these changes have great impact on her ability to sing during the pregnancy and postpartum periods. The voice may be altered positively or negatively by the release of hormones. The body undergoes many changes that affect the posture and breathing required for singing. Most notably, the abdominal muscles are greatly impacted by the pregnancy. They are stretched by the growing uterus, and this affects their function. In addition, the linea alba (the connective tissue between the halves of the rectus abdominis) is softened by hormonal increases and subject to stretching as the uterus grows, predisposing it to weakness. Since the other abdominal muscles attach to the linea alba via connective tissue, maintaining the integrity of the linea alba during pregnancy and postpartum is vital to the operational function of the abdominal muscles. Protecting the vulnerable linea alba must be deliberately undertaken in two parts. First, conscious exercise is needed to preserve the linea alba during pregnancy and to rehabilitate it after pregnancy. Targeted exercises strengthen the transverse abdominis and shorten and approximate the two halves of the rectus abdominis. Second, modifications in daily movement are necessary to protect the linea alba while performing routine activities. Cesarean sections present additional surgical concerns for singers, including abdominal incisions, use of medication, and the rare need for general anesthesia via intubation. Recovery from a cesarean can be difficult due to abdominal pain, yet steps may be taken to speed healing at the hospital and at home. This paper provides an overview of how pregnancy affects the singer, discusses the effects of pregnancy and cesarean section, and provides a plan to protect the abdominal muscles during pregnancy and rehabilitate them in the postpartum period. It combines information from the fields of physical therapy, medicine, and surgery into a guide for the singer and voice teacher.

Description
Achievement of many long-term goals requires sustained practice over long durations. Examples include goals related to areas of high personal and societal benefit, such as physical fitness, which requires a practice of frequent exercise; self-education, which requires a practice of frequent study; or personal productivity, which requires a practice of performing work. Maintaining these practices can be difficult, because even though obvious benefits come with achieving these goals, an individual's willpower may not always be sufficient to sustain the required effort. This dissertation advocates addressing this problem by designing novel interfaces that provide people with new practices that are fun and enjoyable, thereby reducing the need for users to draw upon willpower when pursuing these long-term goals. To draw volitional usage, these practice-oriented interfaces can integrate key characteristics of existing activities, such as music-making and other hobbies, that are already known to draw voluntary participation over long durations. This dissertation makes several key contributions to provide designers with the necessary tools to create practice-oriented interfaces. First, it consolidates and synthesizes key ideas from fields such as activity theory, self-determination theory, HCI design, and serious leisure. It also provides a new conceptual framework consisting of heuristics for designing systems that draw new users, plus heuristics for making systems that will continue drawing usage from existing users over time. These heuristics serve as a collection of useful ideas to consider when analyzing or designing systems, and this dissertation postulates that if designers build these characteristics into their products, the resulting systems will draw more volitional usage. To demonstrate the framework's usefulness as an analytical tool, it is applied as a set of analytical lenses upon three previously-existing experiential media systems. To demonstrate its usefulness as a design tool, the framework is used as a guide in the development of an experiential media system called pdMusic. This system is installed at public events for user studies, and the study results provide qualitative support for many framework heuristics. Lastly, this dissertation makes recommendations to scholars and designers on potential future ways to examine the topic of volitional usage.

Description
Arnold Schoenberg's 1908-09 song cycle, Das Buch der hängenden Gärten [The Book of the Hanging Gardens], opus 15, represents one of his most decisive early steps into the realm of musical modernism. In the midst of personal and artistic crises, Schoenberg set texts by Stefan George in a style he called "pantonality," and described his composition as radically new. Though stylistically progressive, however, Schoenberg's musical achievement had certain ideologically conservative roots: the composer numbered among turn-of-the-century Viennese artists and thinkers whose opposition to the conventional and the popular--in favor of artistic autonomy and creativity--concealed a reactionary misogyny. A critical reading of Hanging Gardens through the lens of gender reveals that Schoenberg, like many of his contemporaries, incorporated strong frauenfeindlich [anti-women] elements into his work, through his modernist account of artistic creativity, his choice of texts, and his musical settings. Although elements of Hanging Gardens' atonal music suggest that Schoenberg valued gendered-feminine principles in his compositional style, a closer analysis of the work's musical language shows an intact masculinist hegemony. Through his deployment of uncanny tonal reminiscences, underlying tonal gestures, and closed forms in Hanging Gardens, Schoenberg ensures that the feminine-associated "excesses" of atonality remain under masculine control. This study draws upon the critical musicology of Susan McClary while arguing that Schoenberg's music is socially contingent, affected by the gender biases of his social and literary milieux. It addresses likely influences on Schoenberg's worldview including the philosophy of Otto Weininger, Freudian psychoanalysis, and a complex web of personal relationships. Finally, this analysis highlights the relevance of Schoenberg's world and its constructions of gender to modern performance practice, and argues that performers must consider interrelated historical, textual, and musical factors when interpreting Hanging Gardens in new contexts.

Description
ABSTRACT This document introduces singers and voice teachers to Dr. Alfred A. Tomatis's listening training method with a particular emphasis on its relevance to singers. After presenting an overview of Tomatis's work in the field of audio-psycho-phonology (circa 1947 through the 1990s) and specific ways that aspects of his theory are relevant to singers' performance skills, this project investigates the impact of listening training on singers by examining published research. The studies described in this document have investigated the impact of listening training on elements of the singer's skill set, including but not limited to measures of vocal quality such as intonation, vocal control, intensity, and sonority, as well as language pronunciation and general musicianship. Anecdotal evidence, presented by performers and their observers, is also considered. The evidence generated by research studies and anecdotal reports strongly favors Tomatis-based listening training as a valid way to improve singers' performance abilities.

Description
Although opera is the last musical genre one typically associates with Latin America, Mexican composer Daniel Catán (1949-2011) found surprising success across the United States and overseas with his opera Florencia en el Amazonas (1996). Catán blends colorful music with literary elements to create a representation of Latin American culture through language, drama, scenery, and music. Among these elements is realism mágico (magical realism), a significant characteristic of Latin American literature. Indeed, the plot of the opera is influenced by Gabriel García Márquez's novel, El amor en los tiempos del cólera (Love in the Time of Cholera, 1985), as well as the poem "Mariposa de obsidiana" (Obsidian Butterfly, 1951) and the short story "La hija de Rappaccini" (Rappaccini's Daughter, 1953), both by Octavio Paz. To create his protagonist in the opera, Florencia Grimaldi, Catán combines the dramatic qualities of several European soprano heroines. This figure's character development is conveyed largely through her Act I, Scene 2, aria, "Florencia Grimaldi," and her Act II, Scene 17, aria, "Escúchame." An overview of the opera places these two arias into context, and their musical content and text-setting are closely examined in relation to the character of Florencia. Finally, how Daniel Catán creates a soprano heroine from the Latin American perspective is discussed.

Description
Libby Larsen is one of the most performed and acclaimed composers today. She is a spirited, compelling, and sensitive composer whose music enhances the poetry of America's most prominent authors. Notable among her works are song cycles for soprano based on the poetry of female writers, among them novelist and poet Willa Cather (1873-1947). Larsen has produced two song cycles on works from Cather's substantial output of fiction: one based on Cather's short story, "Eric Hermannson's Soul," titled Margaret Songs: Three Songs from Willa Cather (1996); and later, My Antonia (2000), based on Cather's novel of the same title. In Margaret Songs, Cather's poetry and short stories--specifically the character of Margaret Elliot--combine with Larsen's unique compositional style to create a surprising collaboration. This study explores how Larsen in these songs delves into the emotional and psychological depths of Margaret's character, not fully formed by Cather. It is only through Larsen's music and Cather's poetry that Margaret's journey through self-discovery and love become fully realized. This song cycle is a glimpse through the eyes of two prominent female artists on the societal pressures placed upon Margaret's character, many of which still resonate with women in today's culture. This study examines the work Margaret Songs by discussing Willa Cather, her musical influences, and the conditions surrounding the writing of "Eric Hermannson's Soul." It looks also into Cather's influence on Libby Larsen and the commission leading to Margaret Songs. Finally, a description of the musical, dramatic, and textual content of the songs completes this interpretation of the interactions of Willa Cather, Libby Larsen, and the character of Margaret Elliot.

Description
The performance of Charles Ives's art songs can be challenging to even the most experienced singers, but to beginning singers, they may be even more so, due to such twentieth-century aspects as polytonality, polyrhythm, tone clusters, aleatoric elements, and quarter tones. However, Ives used previously existing material, often familiar hymn tunes, as the foundation for many of his art songs. If beginning students first are exposed to this borrowed material, such as a simple hymn tune, which should be well within even the most experienced singer's comfort range, they can then learn this tune first, as a more simplistic reference point, and then focus on how Ives altered the tunes, rather then having to learn what seems like an entirely new melody. In this way, Ives's art songs can become more accessible to less-experienced singers. This paper outlines a method for researching and learning the borrowed materials in Ives's songs that utilize them, and reviews materials already commonly used by voice teachers to help beginning students learn their music. By combining this method, which focuses on the borrowed materials, with standard practices teachers can then help their beginning students more easily learn and perform Ives's art songs. Four songs, from the set "Four Hymn Tune Settings" by Charles Ives are used to illustrate this method.

Description
Emily Dickinson is a well-known American poet of the nineteenth century, and her oeuvre consists of nearly 2,000 posthumously published poems. Written largely in hymn form with unique ideas of punctuation and grammar, her poetry attracts composers with its inherent musicality. The twentieth-century American composers Aaron Copland, Ernst Bacon, Lee Hoiby, and Gordon Getty have created song settings of Dickinson's poetry. Copland's song cycle Twelve Poems of Emily Dickinson (1949-50) is admired by many as an illustration of poetry; however, the Dickinson cycles by Bacon, Hoiby, and Getty are also valuable, lesser-known representations of her writing. Settings of one poem, "There came a Wind like a Bugle--", are common among Copland's Twelve Poems, Bacon's cycle Songs from Emily Dickinson: Nature, Time, and Space (1930), Hoiby's Four Dickinson Songs (1988), and Getty's The White Election (1982). These latter three settings have previously undergone some theoretical analysis; however, this paper considers a performance analysis of these songs from a singer's point of view. Chapter 1 provides background for this study. Chapter 2 consists of a biographical overview of Dickinson's life and writing style, as well as a brief literary analysis of "There came a Wind like a Bugle--". Chapters 3, 4, and 5 discuss Ernst Bacon, Lee Hoiby, and Gordon Getty, respectively; each chapter consists of a short biography of the composer and a discussion of his writing style, a brief theoretical analysis of his song setting, and commentary on the merits of his setting from the point of view of a singer. Observations of the depiction of mood in the song and challenges for the singer are also noted. This paper provides a comparative analysis of three solo vocal settings of one Emily Dickinson poem as a guide for singers who wish to begin studying song settings of this poem. The Bacon and Hoiby settings were found to be lyrical, tonal representations of the imagery presented in "There came a Wind like a Bugle--". The Getty setting was found to be a musically starker representation of the poem's atmosphere. These settings are distinctive and worthy of study and performance.

Description
Zwischen in the German language means `between,' and over the past century, as operatic voices have evolved in both range and size, the voice classification of Zwischenfach has become much more relevant - particularly to the female voice. Identifying whether nineteenth century composers recognized the growing opportunities for vocal drama, size, and range in singers and therefore wrote roles for `between' singers; or conversely whether, singers began to challenge and develop their voices to sing the new influx of romantic, verismo and grand repertoire is difficult to determine. Whichever the case, teachers and students should not be surprised about the existence of this nebulous Fach. A clear and concise definition of the word Fach for the purpose of this paper is as follows: a specific voice classification. Zwischenfach is an important topic because young singers are often confused and over-eager to self-label due to the discipline's excessive labeling of Fachs. Rushing to categorize a young voice ultimately leads to misperceptions. To address some of the confusion, this paper briefly explores surveys of the pedagogy and history of the Fach system. To gain insights into the relevance of Zwischenfach in today's marketplace, I developed with my advisors, colleagues and students a set of subjects willing to fill out questionnaires. This paper incorporates current interviews from two casting directors of national and international opera houses, an emerging American mezzo-soprano, a mid-career working European mezzo-soprano, an operatic stage director, an education director for opera houses and a composer. These interviews, along with modern examples of zwischenfach voices are analyzed and discussed.
