Our last house, before we moved down here to Malvern had originally been an extension to the Victorian House next door. Our (wonderfully grand) sitting room/lounge had originally been built as a small ballroom, and we did a lot of work exposing the original wainscotting and restoring the ceiling.
I used to enter the house, when the house was empty and I was alone and very often, as I opened the front door, I could hear the sound of a piano playing in the lounge.
We didn't have a piano, nor did any of our neighbours. Not in the twentieth century anyway.
I liked it, whoever it had been, they were good! The repertoire was not what I would have chosen, parlour ballads and some light operetta, but it was music for parties, and the house always felt like a happy place.
Cheers
Dave
