When we speak, we use different variations of pitch. When giving speeches we use these different tones to be expressive. Optimum pitch is defined as “the level at which people can produce their strongest voice with minimal effort and that allows variation up and down the musical scale” (Turner, Osborn, Osborn, & Osborn, 2018). An example of someone using their optimum pitch is former President Barack Obama. When he delivered speeches he would talk in a clear, strong, rich tone that was pleasing to his listeners. He produced a ideal vocal quality which projected onto the audience.
