We have a small room off the dining room which we call the piano room (because, well, the piano resides there, and not much else- a small desk and a few chairs). This room gets the morning sun, and a vine grows over the window in the summer. As a result of this, I haven't cleaned the window in a while, because one can't disturb a vine which is growing so vigorously. It would just be wrong.
The room is painted a yellowish-green, and I've hung some leaf plates above the piano. The piano itself is very old and made of walnut, I think. It's also out of tune, because the last piano tuner who worked on it, made some rather insulting comments about it (i.e. something along the lines of 'this reminds me of a model T Ford') and I suppose I'm still smarting from that. The sound which emanates from this vintage instrument has a saloon-ish quality about it. This used to be considered by my children to be an instrument of torture, but I can safely say that after about 11 years or so, they are starting to enjoy it.
As with any surface, things tend to accumulate there over time; a bust of a little french girl, some photos, plates, plastic music trophies. Dust.
Music adds to the ambiance of a home, don't you think? Especially live music. Especially the theme from the Super Mario Video game. We're all about culture around here.
