Audiences during Shubbak's 2019 festival

Relaxed performances are primarily designed for people who may find visiting a theatre daunting. They are designed to be welcoming for a diverse audience and provide a relaxed environment to accommodate different people with different needs. At relaxed performances and venues, shows have been adapted to suit people who might be unable to sit still and quiet for a long time and find going to the theatre daunting. Usually, these are adults or children with learning difficulties, autism or sensory communication disorders.
