Digestion, blood pumping through our veins, and breathing are just a few of the functional rhythms inside us that we rely upon to live. When we are unwell, we sometimes say that we are feeling ‘out of sorts’ or ‘out of sync’; it is a bit like losing one’s rhythm. We know when we have found it again because we feel more ‘in the groove’. Music therapy can be helpful in re-discovering that intrinsic rhythm when retrieving it ourselves is a struggle (as with mood and social cognitive disorders; rehabilitation from brain injury, stroke, or heart attack; cerebral palsy; Huntington’s disease; etc.).
