CYOA is a prototype of an iPhone application that produces a single, generative, musical work. This document details some of the thoughts and practices that informed its design, and specifically addresses the overlap between application structure and musical form. The concept of composed instruments is introduced and briefly discussed, some features of video game design that relate to this project are considered, and some specifics of hardware implementation are addressed.

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.

Mongolian overtone singing (höömii) and Mongolian wrestling songs (tsols) are vocal styles that evoke physical and mental strength in the vocalist through the accessing of nature. The phrase “höömii-tsol-thinking computer” conveys my end-goal while composing, performing, and researching for my original composition strong.mng. I wanted to create a work in which the computer would be informed by the performance methods and philosophies employed during Mongolian höömii and tsols.
Strong.mng is a 25-minute production for dancer, live digital illustrator, and overtone singer with a laptop computer serving as both a fixed and interactive responsive musical instrument. The music draws upon themes from höömii and tsols through the lens of virtual fieldwork, which was the research method I used to inform strong.mng. Through the composing and performing of strong.mng, I arrived at the following three-part hypothesis: firstly, the development of a robust symbiotic relationship between höömii, tsols, and today’s electronic music technology may transform the technological devices used into agents of deep ecology and bodily interconnectedness. Secondly, this transformation may metamorphose the performer into a more courageous being who is strengthened both physically and mentally by the Mongolian belief that, when performing höömii and tsols, the musician is drawn into kinship with nature. Lastly, I believe some computer music is restrained in its potential by techno-somatic discreteness as well as anthropocentrism, and that applying philosophies from höömii and tsols can help move computer music more towards a physically embodying means of sonification; one that is also akin with the natural world.
