If the dog walks over and contemptuously pees on your leg while your playing...or on the instrument...then you may be sure he doesn't like the music. If he leaves the room, he doesn't like it either. If he stays and howls, chances are reasonably good that he does like it, but there may be exceptions to that. There are high-priced animal psychologists in Hollywood who can settle this mystery for you for a mere few thousand dollars....- LH
