When I was a kid we had a daschund who loved my dad’s piano playing. He would lay on dad’s left foot and howl along in tune, but only to the music of two composers that he apparently liked! I wish I remembered which composers it was but I don’t. I’m thinking one was Motzart but I’m not sure. My Labrador now sometimes sings to my violin playing but not to piano although he loves when I play piano. He always wants to come inside to be close by if he hears me playing. Sometimes he even squeezes under the piano bench, which is a very tight fit.
