A singer is someone who vocalizes musical sounds with tone and pitch, and uses his or her own voice to produce music. Singers may sing solo or in a group, and are oftentimes accompanied by instrumental music. The physical act of singing occurs as air passes through the larynx, throat, and mouth, and it’s interesting to note that vocal resonation in singing involves seven areas of the human body: chest, tracheal tree, larynx, pharynx, oral cavity, nasal cavity, and the sinuses. A singer is an artist or performer who crafts a vocal song using various techniques and training. Singers often practice daily and will hire professional voice coaches to help them hone their craft. Singers may write their own music or sing music written by others. In addition to singing, singers may work as music teachers or voice coaches.
