When I play my saxophone or something along that line, my dogs howl .... loudly. Half the time I don't know if they are protesting or singing along. I think it's protesting. When I play bass or harmonica, they gather .... watch me and listen. I could tell some funny stories about both. I had one (now dead) that seemed to like to listen, but any time I played this "one" song ...... she would about knock down the door to get out of there. One day I had the main door into the house open, but the screen door shut and locked. She hit that screen door so fast, and well ..... not only broke the lock, but damaged the door pretty good. She refused to come back into the house until I had the guitar put up. But turn on the stereo system and put on Santana playing Samba Pa Ti ...... and she was all ears, and loved that song ... My cat, she just runs away and hides. She doesn't show back up until she thinks it's safe.
