The attractiveness or exciting qualities of a singer or recording are subjective and vary between listeners, cultures, and time periods. Different vocal styles are considered to be desirable in different cultures. In Southeast Asia, for example, female pop singers sing with a very high-pitched, nasal tone; while this singing style would be unlikely to create positive responses for most Western listeners, for Asian audiences, the sound of the most popular singers hitting high notes creates a physiological response of emotional excitement. Even within a single culture, the singing styles vary widely from one style to another. Within the death metal fan subculture, the low, guttural sound of a well-performed "death grunt" is widely admired; for a typical Western pop or rock listener, though, this type of singing would elicit only puzzlement, not excitement.
