Hello everyone! A good friend of mine is trying to write an instrumental song (mostly piano) for my roommate's Grandmother who recently passed away. His Grandfather is deaf (and so was his Grandmother), and we are trying to figure out if there's something unique we could do with the song, something that would stand out for his Grandfather. I'm sure everyone has their favorites, but is there unique things anyone could think to do with a song? Any help would be greatly appreciated. Thank you!
