I was wondering if anyone could have an idea just from drawings what could be the best angle (choices 1 to 4 on the picture) for the piano to get an optimal sound, especially for the bass. Maybe someone here knows, for example, that bass waves tend to come out of the piano in a certain direction, etc.

On the drawing, blue indicates outside walls, and since they get cold in winter I will keep the piano close to the interior walls (in grey).

Thanks in advance !


I think you'll find placement makes no difference at all in the sound of the bass. The wavelength is so long compared to the room's dimensions that any placement is effectively the same.

I've found that having the soundboard of a grand piano parallel to the floor leads to greater enjoyment.

Thanks AndyJ ! smile

That's what I was thinking too - that the difference would probably be very small regardless of the angle.

Why limit your options unnecessarily? Unless you live in northern Wisconsin in an 80 year old farmhouse with no insulation in the walls, you really don't need to worry about the exterior walls being so cold as to present a problem to a piano located six inches or a foot away. Windows with direct sunlight are a different story, of course.

43.7642245678990986 degrees. Purple walls are best for optimal sound transmission.
