Description
This philosophical inquiry explores the work of philosophers Gilles Deleuze and Félix Guattari and posits applications to music education. Through the concepts of multiplicities, becoming, bodies without organs, smooth spaces, maps, and nomads, Deleuze and Guattari challenge prior and current understandings of existence. In their writings on art, education, and how might one live, they assert a world consisting of variability and motion. Drawing on Deleuze and Guattari's emphasis on time and difference, I posit the following questions: Who and when are we? Where are we? When is music? When is education? Throughout this document, their philosophical figuration of a rhizome serves as a recurring theme, highlighting the possibilities of complexity, diverse connections, and continual processes. I explore the question "When and where are we?" by combining the work of Deleuze and Guattari with that of other authors. Drawing on these ideas, I posit an ontology of humans as inseparably cognitive, embodied, emotional, social, and striving multiplicities. Investigating the question "Where are we?" using Deleuze and Guattari's writings as well as that of contemporary place philosophers and other writers reveals that humans exist at the continually changing confluence of local and global places. In order to engage with the questions "When is music?" and "When is education?" I inquire into how humans as cognitive, embodied, emotional, social, and striving multiplicities emplaced in a glocalized world experience music and education. In the final chapters, a philosophy of music education consisting of the ongoing, interconnected processes of complicating, considering, and connecting is proposed. Complicating involves continually questioning how humans' multiple inseparable qualities and places integrate during musical and educative experiences. Considering includes imagining the multiple directions in which connections might occur as well as contemplating the quality of potential connections. Connecting involves assisting students in forming variegated connections between themselves, their multiple qualities, and their glocal environments. Considering a rhizomatic philosophy of music education includes continually engaging in the integrated processes of complicating, considering, and connecting. Through such ongoing practices, music educators can promote flourishing in the lives of students and the experiences of their multiple communities.

Description
Jazz continues, into its second century, as one of the most important musics taught in public middle and high schools. Even so, research related to how students learn, especially in their earliest interactions with jazz culture, is limited. Weaving together interviews and observations of junior and senior high school jazz players and teachers, private studio instructors, current university students majoring in jazz, and university and college jazz faculty, I developed a composite sketch of a secondary school student learning to play jazz. Using arts-based educational research methods, including the use of narrative inquiry and literary non-fiction, the status of current jazz education and the experiences by novice jazz learners is explored. What emerges is a complex story of students and teachers negotiating the landscape of jazz in and out of early twenty-first century public schools. Suggestions for enhancing jazz experiences for all stakeholders follow, focusing on access and the preparation of future jazz teachers.

Description
William Levi Dawson (1899-1990), director of the Tuskegee Institute Choir from 1931 to 1956, was one of the most important arrangers of Negro spirituals in the twentieth century. He is also remembered as an outstanding composer, conductor, speaker, and leader of festival choruses. His arrangements are still sung by choirs all over the world. Save a small number of dissertations and various articles, however, very little has been written about him. In fact, almost no significant writing has been undertaken utilizing the Dawson papers held at the Manuscript, Archives, and Rare Books Library at Emory University in Atlanta, Georgia. This study utilizes that collection in examining four areas of Dawson's life: his work as a composer, his work as an arranger of Negro spirituals, his work as a choral conductor and music pedagogue, and his life as an African American man living in segregated times. Dawson is shown as a thoughtful, deliberate practitioner of his art who built his career with intention, and who, through his various activities, sought both to affirm the traditional music of his people and to transcend his era's problems with the definitions, associations, and prejudices attached to the term "race." Using a diverse selection of letters, notes, and speeches held in the archive, it is possible to develop a fuller, more nuanced portrait of Dawson. Through a thorough examination of a select few of these documents, his growth can be traced from a young composer living in Chicago, to a college choral director dealing with the realities of racial inequality in the mid-twentieth century, to a seasoned, respected elder in his field, endeavoring to pass on to others knowledge of the music he spent his life arranging and teaching.

Description
This descriptive research study explored practicing Board-Certified Music Therapists' engagement in self-care as needed from the impact of stress and burnout, as well as perceptions of the music therapy profession and professional association. An online survey was completed by 829 practicing board certified music therapists. Mean scores and percentages of nominal variables were generated from an independent sample. ANOVA was used to compare mean scores of dependent variables with independent variables of two or more categories. Open-ended responses generated extensive qualitative data about stress/burnout, job satisfaction, motivation, and self-care. Those who are not currently members of AMTA reported affordability as the primary reason for not being members. Despite some negative perceptions about the profession and professional association, a significant number of music therapists expressed a passion for what they do. Music therapists appear to have a solid grasp on professional responsibilities and ethics. Although respondents reported an overall high level of job satisfaction, a substantial number agreed that they have considered leaving the profession. Low salary was the most commonly acknowledged reason, followed by the continued need to "sell" music therapy, burnout, stress, limited work opportunities, and workplace politics. Respondents identified healthy diet and rest as primary activities of self-care, followed by recreation/leisure time with loved ones, exercise, hobbies, and prayer. Music therapists reportedly continue to feel motivated and inspired in the profession predominantly because of the gratification/satisfaction of the results of their work, followed by engagement in self-care, loving the work regardless of income, attending conferences and symposiums, diversification among various populations, and keeping professional life separate from personal life. ANOVA results indicated that job satisfaction and engagement in self-care likely increase with age; job satisfaction is higher among married music therapists, those with children, and those with more than 30 years in practice; and those with no children and those with a master's or doctorate degree were more likely to engage in self-care. A variety of implications and recommendations are explored.

Description
The brain is a fundamental target of the stress response that promotes adaptation and survival but the repeated activation of the stress response has the potential alter cognition, emotion, and motivation, key functions of the limbic system. Three structures of the limbic system in particular, the hippocampus, medial prefrontal cortex (mPFC), and amygdala, are of special interest due to documented structural changes and their implication in post-traumatic stress disorder (PTSD). One of many notable chronic stress-induced changes include dendritic arbor restructuring, which reflect plasticity patterns in parallel with the direction of alterations observed in functional imaging studies in PTSD patients. For instance, chronic stress produces dendritic retraction in the hippocampus and mPFC, but dendritic hypertrophy in the amygdala, consistent with functional imaging in patients with PTSD. Some have hypothesized that these limbic region's modifications contribute to one's susceptibility to develop PTSD following a traumatic event. Consequently, we used a familiar chronic stress procedure in a rat model to create a vulnerable brain that might develop traits consistent with PTSD when presented with a challenge. In adult male rats, chronic stress by wire mesh restraint (6h/d/21d) was followed by a variety of behavioral tasks including radial arm water maze (RAWM), fear conditioning and extinction, and fear memory reconsolidation to determine chronic stress effects on behaviors mediated by these limbic structures. In chapter 2, we corroborated past findings that chronic stress caused hippocampal CA3 dendritic retraction. Importantly, we present new findings that CA3 dendritic retraction corresponded with poor spatial memory in the RAWM and that these outcomes reversed after a recovery period. In chapter 3, we also showed that chronic stress impaired mPFC-mediated extinction memory, findings that others have reported. Using carefully assessed behavior, we present new findings that chronic stress impacted nonassociative fear by enhancing contextual fear during extinction that generalized to a new context. Moreover, the generalization behavior corresponded with enhanced functional activation in the hippocampus and amygdala during fear extinction memory retrieval. In chapter 5, we showed for the first time that chronic stress enhanced amygdala functional activation during fear memory retrieval, i.e., reactivation. Moreover, these enhanced fear memories were resistant to protein synthesis interference to disrupt a previously formed memory, called reconsolidation in a novel attempt to weaken chronic stress enhanced traumatic memory. Collectively, these studies demonstrated the plastic and dynamic effects of chronic stress on limbic neurocircuitry implicated in PTSD. We showed that chronic stress created a structural and functional imbalance across the hippocampus, mPFC, and amygdala, which lead to a PTSD-like phenotype with persistent and exaggerated fear following fear conditioning. These behavioral disruptions in conjunction with morphological and functional imaging data reflect a chronic stress-induced imbalance between hippocampal and mPFC regulation in favor of amygdala function overdrive, and supports a novel approach for traumatic memory processing in PTSD.

Description
The purpose of this study was to compare perceptions of success and failure, attributions of success and failure, predictions of future success, and reports of out-of-class engagement in composition among middle school band students composing in open task conditions (n = 32) and closed task conditions (n = 31). Two intact band classes at the same middle school were randomly assigned to treatment groups. Both treatment groups composed music once a week for eight weeks during their regular band time. In Treatment A (n = 32), the open task group, students were told to compose music however they wished. In Treatment B (n = 31), the closed task group, students were given specific, structured composition assignments to complete each week. At the end of each session, students were asked to complete a Composing Diary in which they reported what they did each week. Their responses were coded for evidence of perceptions of success and failure as well as out-of-class engagement in composing. At the end of eight weeks, students were given three additional measures: the Music Attributions Survey to measure attributions of success and failure on 11 different subscales; the Future Success survey to measure students' predictions of future success; and the Out-of-Class Engagement Letter to measure students' engagement with composition outside of the classroom. Results indicated that students in the open task group and students in the closed task group behaved similarly. There were no significant differences between treatment groups in terms of perceptions of success or failure as composers, predictions of future success composing music, and reports of out-of-class engagement in composition. Students who felt they failed at composing made similar attributions for their failure in both treatment groups. Students who felt they succeeded also made similar attributions for their success in both treatment groups, with one exception. Successful students in the closed task group rated Peer Influence significantly higher than the successful students in the open task group. The findings of this study suggest that understanding individual student's attributions and offering a variety of composing tasks as part of music curricula may help educators meet students' needs.

Description
Chronic restraint stress impairs hippocampal-mediated spatial learning and memory, which improves following a post-stress recovery period. Here, we investigated whether brain derived neurotrophic factor (BDNF), a protein important for hippocampal function, would alter the recovery from chronic stress-induced spatial memory deficits. Adult male Sprague-Dawley rats were infused into the hippocampus with adeno- associated viral vectors containing the coding sequence for short interfering (si)RNA directed against BDNF or a scrambled sequence (Scr), with both containing the coding information for green fluorescent protein to aid in anatomical localization. Rats were then chronically restrained (wire mesh, 6h/d/21d) and assessed for spatial learning and memory using a radial arm water maze (RAWM) either immediately after stressor cessation (Str-Imm) or following a 21-day post-stress recovery period (Str-Rec). All groups learned the RAWM task similarly, but differed on the memory retention trial. Rats in the Str-Imm group, regardless of viral vector contents, committed more errors in the spatial reference memory domain than did non-stressed controls. Importantly, the typical improvement in spatial memory following recovery from chronic stress was blocked with the siRNA against BDNF, as Str-Rec-siRNA performed worse on the RAWM compared to the non-stressed controls or Str-Rec-Scr. These effects were specific for the reference memory domain as repeated entry errors that reflect spatial working memory were unaffected by stress condition or viral vector contents. These results demonstrate that hippocampal BDNF is necessary for the recovery from stress-induced hippocampal dependent spatial memory deficits in the reference memory domain.

Description
This study investigates ways in which music teachers make personal sense of their professional selves and their perceptions of their places within the broader landscape of music education relative to other types of music teachers in school and community settings. A social phenomenological framework based on the writing of Alfred Schutz was used to examine how participants constructed a sense of self in their social worlds and how they both shaped and were shaped by their social worlds. Eight music teachers participated in this study and represented differing types of music teaching careers, including: public school general music teaching and ensemble directing; independent studio teaching and teaching artistry; studio lessons, classes, and ensembles at community music centers; church ensemble directing; and other combinations of music teaching jobs throughout school and community settings. Data were collected from in-depth interviews, observations of the music teachers in their various teaching roles, and artifacts related to their music teaching positions. Research questions included: Who do the participants conceive of themselves to be as music professionals and music teachers; How do they construct and enact their professional selves, including their teaching selves; How is their construction of professional self, including teaching self, supported and sustained by interactions in their social worlds; and, What implications does this have for the music profession as a whole? After developing a professional portrait of each participant, analysis revealed an overall sense of professional self and various degrees of three role-taking selves: performing, teaching, and musical. Analysis also considered sense of self in relation to social worlds, including consociates, contemporaries, predecessors, and successors, and the extent to which performing, teaching, and musical selves were balanced, harmonized, or reconciled for each participant. Social worlds proved influential in terms of participants' support for sense of self. Participants who enacted the most harmonized, reconciled senses of self appeared to have a professional self that was grounded in a strong sense of musical self, enabling them to think and act flexibly. Participants whose professional selves were dominated by a strong sense of teaching or performing self seemed confined by the structures of their social world particular to teaching or performing, lacked a sense of musical self, and were less able to think and act flexibly. Findings suggest that active construction of consociate relationships throughout varied social worlds can support a balanced, reconciled conception of self, which informs teaching practice and furthers the ability to act in entrepreneurial ways.

Description
The purpose of this study was to investigate the attitudes, preferences, and practices of Arizona high school choral directors towards sight-singing skills, and student success in group sight-singing evaluations, the teaching of sight singing including preference for a specific sight-singing system, and the instructional practices employed in daily rehearsals. High school choral directors from the state of Arizona (N = 86) completed an online researcher-designed questionnaire that gathered demographic information as well as information regarding directors' attitudes towards sight-singing instruction, which exercises are used for sight-singing instruction, and directors' self-perceived ability not only to sight sing but also to teach sight singing. Independent variables such as teaching experience, level of education, the system they were trained to use as a student, the system they currently use in the classroom, their self-perceived ability to sight sing, their self-perceived ability to teach sight singing, their choir's sight-singing rating at festival, and their daily instructional practices (as measured by minutes per week of sight-singing instruction) were used to investigate potential differences in attitudinal responses. Multivariate analyses of variance were conducted to investigate potential differences in responses according to various independent variables. Significant differences were found in responses to statements of the importance of sight-singing instruction according to level of teaching experience and time spent on sight-singing instruction in the classroom. No significant differences were found for statements of directors' attitudes toward sight-singing instruction according to level of education or prior training. Results indicate that Arizona high school directors are a seasoned and highly education group of professionals who understand and believe strongly that sight-singing instruction should be a part of their choral music rehearsals. These directors use a variety of systems and resources to teach sight-singing and all dedicate time to sight-singing each week in their rehearsals. Despite the overwhelming support for teaching sight-singing in daily choral rehearsals, there is a lack of participation in choral adjudication festivals where group sight singing is assessed. Further research is suggested to investigate the lack of participation of Arizona high school choral teachers in the group sight-singing component of the state choral adjudication festivals.
