This past weekend, I moved our piano to the opposite (and smaller) wall in our living room. It makes more sense and felt like a huge breath of fresh air to finally have it moved. This is how I quickly styled it (using everything I already had).....
sorry for the bad iPhone pic!
In my opinion, you can choose different approaches to decorating around a piano depending on your personal preference, style or need.
Since my piano sits in our living room, I wanted a simple and formal look. However, if our piano sat in our family room, I might consider something like this using family photos:
If you want a casual look, but are not up to the task of hanging a gallery wall, consider a layered look. I really love this look too....
OR add an oversized mirror or an oversized piece of art....
(BTW, love how this piano is a matte black!)
And, if by chance, you happen to be renovating and want to include your piano in the design, I really like this idea of adding a built-in or molding details to distract your view from the piano, but add a great display of accessories!
