The old piano in the corner of the living room stood silent, its keys yellowed with age. Sarah ran her fingers across them, remembering her mother's soft melodies. She had loved the music, the way it filled the room. She felt a deep connection to this house, to its history, though she couldn't explain it.

The silence of the piano became heavier, the music seeming to fade into a discordant echo.
