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
Digital sound synthesis allows the creation of a great variety of sounds. Focusing on interesting or ecologically valid sounds for music, simulation, aesthetics, or other purposes limits the otherwise vast digital audio palette. Tools for creating such sounds vary from arbitrary methods of altering recordings to precise simulations of vibrating objects. In this work, methods of sound synthesis by re-sonification are considered. Re-sonification, herein, refers to the general process of analyzing, possibly transforming, and resynthesizing or reusing recorded sounds in meaningful ways, to convey information. Applied to soundscapes, re-sonification is presented as a means of conveying activity within an environment. Applied to the sounds of objects, this work examines modeling the perception of objects as well as their physical properties and the ability to simulate interactive events with such objects. To create soundscapes to re-sonify geographic environments, a method of automated soundscape design is presented. Using recorded sounds that are classified based on acoustic, social, semantic, and geographic information, this method produces stochastically generated soundscapes to re-sonify selected geographic areas. Drawing on prior knowledge, local sounds and those deemed similar comprise a locale's soundscape. In the context of re-sonifying events, this work examines processes for modeling and estimating the excitations of sounding objects. These include plucking, striking, rubbing, and any interaction that imparts energy into a system, affecting the resultant sound. A method of estimating a linear system's input, constrained to a signal-subspace, is presented and applied toward improving the estimation of percussive excitations for re-sonification. To work toward robust recording-based modeling and re-sonification of objects, new implementations of banded waveguide (BWG) models are proposed for object modeling and sound synthesis. Previous implementations of BWGs use arbitrary model parameters and may produce a range of simulations that do not match digital waveguide or modal models of the same design. Subject to linear excitations, some models proposed here behave identically to other equivalently designed physical models. Under nonlinear interactions, such as bowing, many of the proposed implementations exhibit improvements in the attack characteristics of synthesized sounds.

Description
The original scope of this project was to have several conducting experiences and written records about the conductor’s experiences. Due to COVID-19, the focus of the paper has shifted to documenting the preparation, rehearsal, and performance "Recombobulation" (2016) by Theresa Martin. Using the templates found in the "Teaching Music Through Performance in Band" book series as a model, combined with the author’s personal narrative of their experience, this paper aims to serve as a resource for both people considering programming this piece of music as well as early career conductors who strive to improve their craft.

Description
Clarinet articulation is a process that uses the tongue to create an interruption in sound production either by contacting the reed or disrupting the air stream. This process occurs inside the mouth and is hidden from direct view. As a result, various solutions were developed in clarinet pedagogy to address the issue of teaching with no visual feedback. Clarinet pedagogy literature consists of language that makes it possible for other clarinetists to discuss, teach, and research various aspects of clarinet playing. The interdisciplinary application of theoretical concepts in linguistics and how they map onto the language of clarinet pedagogy offers a new perspective for understanding the teaching methods used for articulation. To provide insight into the relationship of language and clarinet pedagogy, an overview of several linguistic theories and concepts, such as Peircean semiotics, metalanguages, discursive strategies, and articulatory phonetics, is presented. Additionally, a brief explanation of articulation techniques (single, multiple, flutter, and slap articulation) and commonly used teaching strategies is outlined. The language used in clarinet pedagogy literature from resources by prominent clarinet pedagogues, such as the works of John Anderson, Joshua Gardner, Michèle Gingras, Eric C. Hansen, Howard Klug, Phillip Rehfeldt, Thomas Ridenour, Heather Roche, Robert Spring, and Rachel Yoder, is surveyed. Pedagogical insights from a linguistic analysis are used to create resources for teaching and/or correcting articulation. Since the interdisciplinary application of linguistics and clarinet pedagogy is an underexplored topic, this research also aims to serve as a basis for further interdisciplinary studies.

Description
This paper highlights a method for jazz transcription, comprehension, and practice to be implemented primarily in applied saxophone instruction with undergraduate students. The purpose is the identify and mend the divide between jazz and classical that appears in academia. This divide is one that came about by necessity in the saxophone’s relative youth in the academic world as it found solid footing in conservatories around the world. A literature review establishes the current state of dialogue between both jazz and classical in the academic saxophone community, including the current state of crossover scholarship that discusses the interaction between multiple genres. This review investigates what serves as pedagogical material in an aural discipline like jazz. A thorough approach to transcription is crucial change to the standard practice of jazz transcription typically employed in applied saxophone studios. This approach takes the focus away from the product and places it on the process. This process is demonstrated through a transcription and deconstruction of Charlie Parker’s “Cheryl.” Though this approach is presented through the perspective of a saxophonist, this process can be applied to any number of instrumental disciplines seeking to understand jazz transcription and improvisation more fully.

Description
While much has been written on the history of Education Concerts in the United States, there is a void in research focused on actual content, structure, and purposes of these concerts. This document seeks to fill this void through a detailed examination of salient aspects of Education Concerts, including programming, structure, rehearsal, and performance considerations. In conjunction with my research, I will draw on my first-hand experience as Associate Conductor of the Seattle Symphony, providing a glimpse into the creative challenges and solutions that confront a contemporary orchestra. Additionally, my research endeavors to discover ways of transforming the historically rigid model of orchestral operations into a structure that embraces diversity, equity, and inclusion, encourages connections, and sparks curiosity. The goal of this research, therefore, is to provide tangible references and practical guidance to the conductor or administrator who is venturing into the richness of Education Concert programming and performance in today’s everchanging orchestral landscape.

During my career as an oboist, I have only played the oboe d’amore one time before this project. I have always wondered why such a beautiful instrument is scarcely
played today, and decided it was time to commission new works that aim to bring back
the instrument’s popularity. Tim Carlos composed Fernweh: Sonata for Oboe d’amore
and Piano and Two Sketches for Oboe d’amore, Guitar, and Percussion. This document
covers the collaborative method Carlos and I experienced, the history of the oboe
d’amore, edits made to the compositions, and most importantly a performer’s guide to
these two new works (discussing both technical and musical challenges.) The recordings
are also included. To purchase either work in its entirety, contact

Description
One way in which public school band directors hone their conducting skills beyond their initial academic training is by attending conducting workshops. These workshops, which usually range in duration from one day to a full week give conductors the opportunity to obtain critical feedback from recognized pedagogues, helping them improve, among other things, their conducting gestures, rehearsal techniques, and score study abilities. Offered at various times throughout the year with many of them taking place during the summer when public school educators do not have teaching responsibilities, most band conducting workshops are designed to be inclusive of anyone in search of professional development opportunities. However, the costs often associated with attending a workshop can be challenging for many people. The goal of this study is to take the potential professional development yielded from a traditional in-person conducting workshop and transition it to a one-on-one online format that will not only allow for similar growth found with traditional in-person workshops, but also provide additional benefits unique to the virtual setting. Based on the findings in this study, the virtual platform has the potential to cover many of the same goals as the traditional workshop. And while there were some components of the traditional workshop that could not be produced virtually, there were some unintended positives that the virtual workshop provided. Among those positives were addressing issues of equity and access, while also building professional relationships, that in turn, could result in graduate school opportunities.

ABSTRACT
COVID-19 has affected every aspect of society, including the performing arts. This study creates a historic record of the impact of the COVID-19 pandemic on Navy Band Southwest (NBSW), located in San Diego, CA. It is an account of Navy Band Southwest’s journey under my direction as the Bandmaster and the transformation from live music performances to performances in the virtual environment from March 2020 until September 2021. The paper details safety protocols developed by the NBSW leadership team that were implemented following Center for Disease Control and Department of Defense overarching guidance. It also examines the process of development of recording techniques, both audio and video, as well as hardware used to create virtual band performances. Chapters cover NBSW operations pre-COVID, development of the virtual music-making process, and the creation of specific projects, including an original commission for wind band that was conceived, composed, rehearsed, and recorded entirely in a virtual environment. This paper aims to capture the perseverance and professionalism of U. S. Navy Sailors and how these musicians adapted to continue making music during forced isolation and quarantine. An archive of selected performances is included with this document.

Description
Many options for mouthpieces and reeds are available to clarinetists, which makes selecting the right equipment complicated. In addition to personal research, potential influences in this process included teachers, professors, and private instructors. To provide some clarity in the current trends impacting the selection of new equipment, a survey of clarinetists was conducted. All participants were asked what equipment they were currently using and to specify what elements of the purchase were most important. Aspects such as price, instructor influence, personal research, conferences, brand loyalty, new releases, and social media were ranked by level of importance. Additionally, questions were asked of participants who taught clarinet about what they recommended to their students at various skill levels. The opinions of clarinetists along with the analysis of the data confirmed which mouthpieces and reeds were being suggested for different skill levels. The results were analyzed by type of career with strong trends in the participants current equipment and their suggested equipment.
