Inclusion criteria  The proposed inclusion criteria for care home residents are as follows:  Participants must be aged 50+ years Participants will be a resident of one of the 12 care homes taking part For each participant, there must be clinical evidence of cognitive impairment. This will be determined by a score of 24 or under on the SMMSE Each participant must display at least one behavioural/psychological symptom of dementia. This will be determined by a score of 4 or higher on the NPI-NH.  The proposed inclusion criteria for care home staff are as follows:  Participants must be aged 18+ years Participants must have worked in the care home for at least 3 months Participants will be required to have in-depth knowledge of the resident participant(s). This will be determined via a screening form for staff to complete based on how well they know the residents. This will be administered prior to the commencement of the study.  Exclusion Criteria  Exclusion criteria for care home residents:  - Participants who's health appears to be at risk which raises the concerns of their sustained involvement with the study. This would be evident from a health assessment from a general practitioner. Given that this is a music therapy study, this could also include people with a hearing impairment.  Exclusion criteria for care home staff:  - Staff who cannot adequately answer on behalf of the residents due to lack of knowledge of the residents.
