It makes me happy. It takes me to new places. It makes me laugh. Occasionally it even gives me goosebumps. It also gets me out of the house and socializing with people. Playing it is even better, and it finely hones hand-eye coordination and fine motor control in the hands, and it keeps the brain active in many ways.
Music is a truly wonderful and precious thing. It's very special, and for many people certain songs hold very deep and personal meanings for them. Really, it's one of the greater points of the human experience. Other animals chirp, and howl, and even sound to be singing at times, but we humans not only use our voices for music we make instruments specifically for it, we have a concept and name for the specific practice of it, and we share it with others specifically as music.
Music is a wonderful thing in that it can make you feel anything. It can take you on adventures, bring back memories, spark your imagination, it can make you happy or sad or passionate, confident, powerful, strong, excited, motivated. There is no feeling that music cannot give.
