What kinds of interventions do you use in hospice?

Hi! I am a board-certified music therapist working in hospice. Recently, I have been feeling like I'm doing a lot of the same stuff, and a lot of it feels like it's just a sing along. I'm wondering, how do you all approach your sessions? Do you primarily use receptive interventions or do you find yourself using more active interventions such as improv or songwriting?

I am also struggling with advocating for music therapy. What are some ways you have educated and advocated that yielded success?
