Managing agitation attacks and other behavioral disturbances through a non-drug, data-driven personalized music intervention. Using a standard wearable and a Spotify account, the Rubato ML algorithm learns which musical attribute creates distinct biological responses for each listener and matches musical attributes such as tempo, key, modality, and structure to cardiac indications such as stress level and heart pace. Rubato's intervention is fully reimbursable for eligible patients at Skilled Nursing Facilities.
