The hotel in Kraków has been decked out in a music motif. It's right across the street from the concert hall, so I suppose there is supposed so be a sort of thematic flow. It serves a strictly visual purpose, however. The notation isn't quite accurate, lines are split into sections as carpeting dictates, etc. So imagine the surprise when one finds the below sitting on the wall behind the front desk:
