Part 1 gives instructions of music activities or music therapy with persons with dementia with references to relevant literature. Part 2 elaborates on subjects such as assessment, music therapy in palliative care, constructive regression, neurological aspects, and music therapy treatment. In part 3 follows a literature review focussing on 73 studies on music and dementia, their methodological design, and on the function of the music.
