This article explores similarities in the music of Billie Eilish and
recordings that induce the Autonomous Sensory Meridian Response (ASMR). Two
complementary approaches are presented. First, the methodology and
preliminary results of an empirical study are reported, which investigates
peoples’ emotional responses to Eilish’s music, mouth-related ASMR sounds
(oral wetness cues, whispering, breathing sounds), and non-mouth ASMR
sounds (tapping, scratching). Second, a new theory of *sonic intimacy* is
presented that draws on similar electroacoustic techniques in the music of
Billie Eilish and Bing Crosby and may account for their popularity during
times of stress and isolation.
