Thanks all for the comments so far. Let me see if I can respond: teacats - the chairs I bought first because I liked them and they were on sale! This was before we had even started looking at pianos (I originally thought we were just going to have an upright). I can't really return them so I think I have to work with them for now or maybe move them to another room in the future, if possible. I was disappointed in the rug color - it was a lot darker than the picture online. I still might be able to return it but I'm contemplating that one. It's a nice rug. I may be able to use it in the dining room instead. I was unsure on having the backs of the chairs to the door - you think that would work? The room is about 18' long x 13' wide. Your suggested artwork is very nice as well. I'll keep it in mind! pipdog - I thought about the corner by the window as well but that means the lid opens to the wall and its in the light and by the furnace register. The lamps aren't staying - they are just temporary for now! aktillery - thank you for that post. There are some other options to consider there. I need to figure out how to make a floor plan to scale so I can see if the room is big enough to have the piano more toward the center. I'm afraid for the piano by the window. My parents' black piano faded over time because it was right by a huge picture window (and still is) cyn427 - I'm having a hard time visualizing what you mean. The corner to the left as you walk in? Seems like the piano would stick out in front of the door but maybe I'll have to try it. It's only 5' long (it's a baby baby!)

Since the piano will be the star of this space, you need to consider these guidelines to ensure high quality sound and a healthy location for the grand. The visual bulk of the piano with the lid open will be sufficient to replace both of your tall casegoods pieces. A good spot might be to place it diagonally across the corner where the keyboard is now. The lid should open against the corner so the sound will be thrown out in to the room and not against the walls. That might also locate the pianist somewhat under the chandelier, which could be helpful in reading music. With the two tall pieces out of the room, move the sofa and sofa table opposite their current location, and then work on placing the two chairs at the best spots for enjoying the music. Perhaps one could go in the corer with the drop leaf table for a reading/listening spot near the window. The other one Might angle near the hearth or under the sconce near the doorway to the other room You'll have to play with them a bit.

As a piano player I would say you need to account for the bench which will not be tucked under the piano and would likely stick out almost as far as the chair you have in the diagram. There wouldn't be any room between the two to walk. I would possibly opt for two love seats (depending on how many seats you would like), or remove the chair and leave the sectional. You could move the chair in front of the window unless you are trying not to block the window.

Another render for perspective
