I wanted to include some additional information related to some research and clinical experiences I had related to the "music of medicine" if I may.  In fact, my father passed away this past year in Feb of 2022 in his nursing home, and he suffered from advanced vascular dementia following a series of strokes that left him totally dependent on others. His short term memory was totally gone and he even often forgot who my mother was, who went to visit him almost daily in his nursing home.  However, when we would play or sing old songs from his youth, his facial expression would light up with delight and he would sing out loud with joy and start talking about old memories associated with certain songs and melodies.  Eric Church's song Springsteen, comes to mind with the lyric "Funny how a melody sounds like a memory to a soundtrack on a July Saturday night..."

 I know one of my earliest clinical experiences was having a patient with Alzheimer's disease (there are over 100 different types of dementia) totally unresponsive with her head down pretty much 24/7.  I read in her medical history and chart that she played piano and retired music teacher.  I wheeled her to a piano and put her hands on it.  To everyone's astonishment, including her daughter who was present, she smiled and started to play song after song after song for over 1 hour until it was lunch time officially on the clinical unit.

Hence, I would argue that "music is medicine for one's heart, mind and soul" and it has healing properties that we are only beginning to understand.  Due to career, family and other obligations, I really haven't played music for about 35 years myself.  It was a total rediscovery of myself, and was very healing and rejuvenating in nature. I started to play and write music again, based on my many and varied life experiences.
