Euphonium Timbre: A Spectral Analysis of Different Mouthpiece Materials

This document explores and utilizes the Digital Audio Workstations (DAW) Audacity and SPEAR (Sinusoidal Partial Editing Analysis and Resynthesis) to create a visual representation of euphonium timbre consisting of complex harmonic structures. Using one mouthpiece model, the Schilke 51 D, this research explores what effect the mouthpiece material has on the amplification of these harmonic structures. Through four exercises geared at different and specific qualities of euphonium sound, this study aims to find the best mouthpiece material for the ideal euphonium sound.
