at the icf where i worked, there used to be 2 lols (little old ladies) in their 80's, who used to come in and sing.
no accompanying instruments; just them 2.....
sorry, i love, i mean LOVE, the elderly.
but these 2 souls missed their calling.
i remember thinking there should have been a reality show called, "WHAT WERE THEY THINKING???"
anyway, they volunteered and didn't last more than 2 weeks.
i find that the right type of music is of great benefit.
if i can find a melodic classical, many pts find it relaxing.
but it really has to be appropriate to the situation.
