Throat singing refers to several vocal practices found in different cultures worldwide. These vocal practices are generally associated with a certain type of guttural voice that contrasts with the most common types of voices employed in singing, which are usually represented by chest (modal) and head registers. Throat singing is often described as evoking the sensation of more than one pitch at a time, meaning that the listener perceives two or more distinct musical notes while the singer is producing a single vocalization.
