Singers also often spend time in rehearsal spaces, where they prepare for upcoming performances or recordings. During rehearsals, singers may work with a band or orchestra to coordinate their performance and perfect their timing. They may also practice choreography and work on their stage presence. Rehearsals can be grueling and repetitive, but they are essential to ensuring a successful performance. In technical terms, singing is a physical process in which air traverses through the larynx, throat, and mouth. The vocal resonation in singing involves seven parts of the human body: the chest, tracheal tree, larynx, pharynx, oral cavity, nasal cavity, and sinuses.
