ASU Electronic Theses and Dissertations
This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.
In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.
Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

Description
Two different techniques utilizing vocalization in clarinet performance were examined through a research study in which one subject (the author) played several tasks utilizing each technique with different played pitches, vocalized pitches, and dynamic levels for each task. The first technique was singing while playing, which is also sometimes referred to as growling. This technique is produced by engaging the vocal folds during regular clarinet performance to create a second vocalized pitch that resonates in the oral cavity and exits through the mouthpiece as part of the same air stream as that used by the vibrating reed. The second technique studied was a much more recently pioneered technique that the author has labelled humming while playing due to its similarity to traditional humming in vocal pedagogy. This technique is produced by filling the oral cavity with air, sealing it off from the rest of the vocal tract using the tongue and soft palate, and humming through the nasal cavity. The cheeks are simultaneously used to squeeze air into the mouthpiece to maintain the clarinet pitch, much like in the technique of circular breathing.
For the study, audio, nasalance, and intraoral pressure data were collected and analyzed. Audio was analyzed using spectrograms and root mean square measurements of sound pressure for intensity (IRMS). Analysis of the nasalance data confirmed the description of the physiological mechanisms used to generate the humming while playing technique, with nasalance values for this technique far exceeding those for both singing while playing and regular playing. Intraoral pressure data showed significant spikes in pressure during the transitions from the regular air stream to air stored in the oral cavity when humming while playing. Audio analysis showed that the dynamic range of each technique is similar to that of regular playing, and that each technique produces very different and distinct aural effects.
This information was then used to help create a method to assist performers in learning how to produce both singing and humming while playing and a resource to help educate composers about the possibilities and limitations of each technique.

Description
Voicing, as it pertains to saxophone pedagogy, presents certain obstacles to both teachers and students simply because we cannot visually assess the internal mechanics of the vocal tract. The teacher is then left to instruct based on subjective “feel” which can lead to conflicting instruction, and in some cases, misinformation. In an effort to expand the understanding and pedagogical resources available, ten subjects—comprised of graduate-level and professional-level saxophonists—performed varied pitch bend tasks while their tongue motion was imaged ultrasonographically and recorded. Tongue range of motion was measured from midsagittal tongue contours extracted from the ultrasound data using a superimposed polar grid. The results indicate variations in how saxophonists shape their tongues in order to produce pitch bends from F6.

Description
As clarinet students progress in their studies, there comes a point at which many are assigned to perform contemporary repertoire that is either overplayed due to accessibility and use in pedagogy, or includes difficult extended techniques like microtones, multiphonics, and more. This project identifies a “gap” in unaccompanied clarinet repertoire and seeks to expand this repertoire by outlining a program of study featuring five newly commissioned unaccompanied clarinet solos through which students can learn both traditional and untraditional techniques. Each of the first four works focus on one aspect of clarinet technique—musicality, the altissimo register, microtones, and multiphonics, respectively—and the final work is a culmination of all these techniques. Included in this document is biographical information for each composer, program notes, a brief description, and a performance guide for each piece. Additionally, each work was recorded by the author and included with this document.
