The pharynges are a special set of muscles, located in the back of their throat and responsible for the production of sound, that help us to speak and sing. They are responsible for the production of the different sounds and tones we can make with our voice, from deep bass to high soprano, and help to shape the words we speak. The pharynges are a complex set of muscles, which consist of three pairs of muscles. Each pair helps to form a different sound; the inner pair form a low register, the middle pair form a mid-tone, and the outer pair form a high register. The muscles also work together to help shape words by pushing the tongue forward and back, as well as raising and lowering the soft palate. The pharynges are an essential part of the speaking and singing process, as they allow us to produce different sounds and tones in our voices. It is thanks to the precise movements of the pharyngeal muscles that we can have varied vocal expressions, enriching our conversations and performances. Furthermore, by learning and exercising these muscles, many singers are able to develop their vocal range and increase the tonal richness of their singing.
