In March 2020, the World Health Organisation (WHO) announced the first global pandemic officially caused by a coronavirus. Public health measures (e.g., increased handwashing, reducing social contacts) were introduced to reduce the rate of transmission, including the closure of spaces and events that would encourage high levels of social interaction along with ‘lockdowns' confining people to the vicinity of their homes. The scale of the disruption caused by the considerable number of cases, and the implementation of lockdowns led to widespread social and emotional disruption. Uncertainty, and financial insecurity arising from these measures cascaded into widespread increases in stress, fear, anxiety, panic attacks, depression, anger, and sleep disorders. This created a unique situation where music-related behaviours and music therapy played an important role. The current chapter reviews how music was used in a range of contexts and settings to support the social, emotional, and physical needs that developed because of the coronavirus pandemic and resulting lockdowns. We aim to highlight the rapid changes that occurred in relation to music use in the general population and music therapy practices as the world adjusted to the new challenges posed by the unprecedented circumstances.
