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
For my creative project, I began an art press that produces small-run vinyl records and artist's books. Initially, the venture began as a means to circumvent record pressing facilities as a vinyl record-cutting service. By the end of this project, the focus shifted to encompass more visual art products than just vinyl records. The project began with vinyl records because I saw a need in the market; in the past decade, the industry has grown dramatically, but the dozen record pressing plants in the country cannot keep up with the demand. Because record pressing companies prioritize large orders, it is difficult for many small bands and independent record labels to produce work on this medium. This is due to the long lead times, high prices, and large minimum order sizes. I located a man in Germany, who invented a machine that makes high-quality, lathe-cut records. I named the project Blushing Soup, as homage to my father, who passed during my first semester of college. It is through his passing that I was able to secure funds to pursue this venture. I brought on a partner, who was more familiar with art and audio recording than myself. In the summer of 2015, we met with this inventor to learn how to use his machine. By October of 2015, a machine of our own had arrived. In early November, Blushing Soup won a grant from the Scottsdale Museum of Contemporary Art. During this time, we released two vinyl records for local bands. For a culminating project, I coordinated a Record Store Day compilation album consisting of six bands featuring. After securing all of the music, the machine started having problems, which forced me to cancel this release. Recognizing the delicacy of the machine, prompted a shift in the aim of Blushing Soup. During this process, I started learning printmaking processes, and I realized that Blushing Soup could function as more than a record cutting service; we could be an art press. In the last few month of this project, I started making artist's books. By the end of April 2016, Blushing Soup will have released vinyl records for two bands, as well as produced four handmade books. This creative project centered around the process of creating art through lathe cutting and printmaking; the objective was not to maximize profits but rather refocus the consumption of art (in a sustainable practice).

Description
"Maybe it's hatred I spew, Maybe it's food for the spirit." "I was not born under a rhyming planet." One of the above quotes is by the famous poet William Shakespeare and the other is by famous rap artist, Eminem. In modern society, many students view the works of artists like Eminem to be understandable and even relatable, while the works of classic poets like Shakespeare are a foreign language. However, when the lines are isolated from their entirety, it is very hard to determine the author of each. This Creative Project focuses on how we can use the works of modern lyricists to help teach the works of traditional literature. Not all students are fond of poetry and many of them view literary analysis as a tedious activity. However, almost everyone enjoys listening to music. This Creative Project shows how listening and interpreting modern song lyrics can be used as a tool to teach literary analysis. One of the main reasons students have difficulty with literary analysis is that they have trouble relating to the wording and style of the literature. By analyzing works more familiar to them (i.e. Kendrick Lamar, The Beatles, or Bob Dylan) the skills will be more easily transferable to analyzing traditional literature. The idea that songwriters can be comparable to famous poets has been picking up traction in recent years. In fact, in 2016, Bob Dylan, American singer and songwriter, was awarded the Nobel Prize for Literature breaking a trend of novels being awarded. This project's goal is to create a class unit for high school English students that teaches analytical skills for contemporary texts (i.e. modern song lyrics). In addition, a unit was created that used the analysis of contemporary lyrics in a middle school Social Studies course. This differentiation shows that development of literary analysis skills are applicable to subjects other than English Literature.

Description
The tradition of building musical robots and automata is thousands of years old. Despite this rich history, even today musical robots do not play with as much nuance and subtlety as human musicians. In particular, most instruments allow the player to manipulate timbre while playing; if a violinist is told to sustain an E, they will select which string to play it on, how much bow pressure and velocity to use, whether to use the entire bow or only the portion near the tip or the frog, how close to the bridge or fingerboard to contact the string, whether or not to use a mute, and so forth. Each one of these choices affects the resulting timbre, and navigating this timbre space is part of the art of playing the instrument. Nonetheless, this type of timbral nuance has been largely ignored in the design of musical robots. Therefore, this dissertation introduces a suite of techniques that deal with timbral nuance in musical robots. Chapter 1 provides the motivating ideas and introduces Kiki, a robot designed by the author to explore timbral nuance. Chapter 2 provides a long history of musical robots, establishing the under-researched nature of timbral nuance. Chapter 3 is a comprehensive treatment of dynamic timbre production in percussion robots and, using Kiki as a case-study, provides a variety of techniques for designing striking mechanisms that produce a range of timbres similar to those produced by human players. Chapter 4 introduces a machine-learning algorithm for recognizing timbres, so that a robot can transcribe timbres played by a human during live performance. Chapter 5 introduces a technique that allows a robot to learn how to produce isolated instances of particular timbres by listening to a human play an examples of those timbres. The 6th and final chapter introduces a method that allows a robot to learn the musical context of different timbres; this is done in realtime during interactive improvisation between a human and robot, wherein the robot builds a statistical model of which timbres the human plays in which contexts, and uses this to inform its own playing.

Description
When dancers are granted agency over music, as in interactive dance systems, the actors are most often concerned with the problem of creating a staged performance for an audience. However, as is reflected by the above quote, the practice of Argentine tango social dance is most concerned with participants internal experience and their relationship to the broader tango community. In this dissertation I explore creative approaches to enrich the sense of connection, that is, the experience of oneness with a partner and complete immersion in music and dance for Argentine tango dancers by providing agency over musical activities through the use of interactive technology. Specifically, I create an interactive dance system that allows tango dancers to affect and create music via their movements in the context of social dance. The motivations for this work are multifold: 1) to intensify embodied experience of the interplay between dance and music, individual and partner, couple and community, 2) to create shared experience of the conventions of tango dance, and 3) to innovate Argentine tango social dance practice for the purposes of education and increasing musicality in dancers.
