Judith, I believe that music can make a large difference in mood, efficiency, and a feeling of general well being. I am a service tech on duplicating equipment, and I work in varied locations. I am not usually able to select what music is playing, if any, where I work. If I am listening to music that I enjoy, I work better, feel better, it makes me just plain feel good. On the other hand if the music is too repetitive,extremely loud or distorted, or a type of music I dislike, it makes me feel trapped, unless I can change it. It actually affects my ability to work, negatively. My father, who has PD, will respond to good music, he will be in a better mood, and less depressed. I also prefer good live music, to recorded, if given the choice. It is amazing how many nice parties, weddings, etc, are accompanied with a disk jockey, and no band! I'd rather have less food, or cheaper decorations, and a good live band, than to listen to tapes, or cds. I can do THAT at home, and I get to pick them! If people continue to shun live music, some day there will be none! One of my hobbies is record collecting, so I know they have their place, but at a catered party? TACKY! (Okay so I come from a family of musicians, and I am predjudiced, but I am RIGHT!) My nephew used to bring a small band to a local nursing home and he really enjoyed the reactions of the residents, and they loved the music! Ken B
