Instrument Construction: An Examination of the Effect of Lead Pipe Design Variability on Tuba Response
Doctor of Musical Arts (DMA)
The document begins with a brief description of the main parts of the tuba: the mouthpiece, the valves, the body and the bell; in addition to a short explanation of the different types of material used to construct brass instruments. This study will function as the first installment of a bigger series exploring the variations in tuba sound when the different main parts are physically altered or swapped for other designs of the same part. This first installment of the series seeks to examine the section of the tuba known as the lead pipe in relation to the implications of varying the lead pipe and observing the effects of these changes. One of the goals of this research is to, through review of related literature, understand the acoustic processes that go into the creation of sound energy within a brass wind instrument. Another purpose of this writing is to discuss, through interviews of experts in the field, the lead pipe and how it is constructed, shaped, and designed, while gaining information as to how it could relate to the sound and response of the tuba. Finally, the primary objective of this study is to gather data through a series of performance tests in which the lead pipe design will be modified with results recorded.
