Stan, the cited YT videos tend to claim the opposite is true. Patients having Music Therapy actually require LESS ATTENTION. That's one of the strong points of the project. It translates to freeing up the staff to perform oft neglected other duties which translates to better overall efficiency and a better work environment. I would expect that patients/residents would require assistance only once or twice per day and that could be combined with mealtimes.

I may be completely wrong but we won't know without trying.
