The Best Place in Your Home to Put Your Piano

In order to decide the best place to position your piano, you first need to know where NOT to put it.

Climate and environment

It’s very important to achieve a constant temperature. Pianos don’t like being in a room that constantly changes temperature (cold at night, hot during the day etc.). Try your best to keep your piano in a room that has the heating on the low side during the winter and is also not too hot and sticky in the summer. A constant temperature of around 20 centigrade (65-70 Fahrenheit) and a humidity level of between 45 and 60 percent are ideal. The easiest way to keep an eye on this is to buy a humidifier gauge and stick it on the wall.

Central heating systems 

A piano’s number one enemy!

When your heating is off during the night, the humidity rises; when it’s switched back on in the morning, the humidity drops. These changes in humidity cause the wood to expand and shrink, causing your piano to go out of tune. Over a long period of time, problems such as loose tuning pins, cracked soundboards, split bridges, wobbly hammers and loose keys can occur.

Central heating can cause the soundboard to crack. Cracked soundboards encourage buzzing noises to appear and in extreme cases, can completely deaden the sound of your piano.

Central heating can dry out the wrest plank. If this happens, the tuning pins that hold the high tension of the strings start to loosen. This results in your piano not being able to stay in tune.

Keep your piano away from heat sources

Keep your piano as far away from radiators or electric heaters as possible. Never put your piano in a room that has under-floor heating! This will completely ruin your piano VERY quickly. If your whole house is fitted with under floor heating then all you can do is place a heavy rug underneath it. This will provide some protection for your piano.

Sunshine is very nice, but pianos don’t really care much for a tan! Direct sunshine coming through a window can be a big problem for your piano… Apart from disturbing the humidity level in your piano, direct sunshine is the cause of another serious issue - fading.

If your piano is under direct sunlight – even for a few days – the wood will start to fade. A high gloss polyester finish can be completely ruined if left under direct sunlight for too long. Sunshine will also knock your piano out of tune.

Solution – keep your piano away from windows that let sunlight through or place a heavy cover over your piano to protect it.

Kitchens are a threat open Entrances

If you have an open floor plan (kitchen and living room together) you must keep your piano as far away from your kitchen as possible. The steam from cooking gets absorbed in the piano’s wood, resulting in an extreme level of humidity. This will cause many problems for your piano including sluggish and sticking keys, slow hammers and dampers, swelling key lead and expanding felts. This excessive humidity can even cause tuning pins, bridge pins and strings to rust.

If, despite your best efforts to keep your piano away from harm. Open entrances and Marble and Ceramic floors Can be the death of any piano Especial anti Grand piano Any piano on Ceramic or Marble should be on a Rug Humidity is almost impossible to control for example if you wash the floor the humidity will go right to the soundboard Opening and closing the door in winter and summer months,

This regulates the moisture content inside the piano.

Drafts

Pianos don’t get on well with drafts either. If your piano is next to a window or an outside door, or beside basement entrance or below an upstairs entrance watch out! You’ll find that keys will start sticking, dampers will stop working and many other small annoyances will interfere with your piano’s performance And Delimitation If you have doubleglazed windows, this will reduce the problem.

Which room is best to put your piano?

For those of you lucky enough to have a purpose-built music room, great.
Otherwise…
Your dining room is probably the next best place to keep your piano. Dining rooms tend to keep a more constant humidity level and have a lower temperature than other rooms in the house.

Question should I leave the lid open

No. Close the lid., it’s highly recommended, the humidity and dust and air exposure are insane. Not only will it make the inside of your piano dirty, but it will also Change the color of your strings and board make it extremely hard to clean. It will give you all kinds of random, tiny but annoying issues with your Soundboard board and humidity issues. Please close your lid if you on an antique piano Your cover will Warp being that it’s made of wood newer pianos are more unlikely Because the piano is mainly made of M.B.F it, s less sensitive to any change in temperature or any stress

To mention also your lid has a folding section this is necessary to keep closed, in a lot of cases piano players open it up to have access of the music stand and to dampen the sound by living the lid closed and the folding section open, always remember to close after playing Your piano.

For an old antique piano, the folding area will cause underneath a declaration on the wood which will be permanent, sometimes Polyester finish also can be affected in some cases it can be resolved by buffing by a train professional.

If you’re going to cover the piano with a piano cover, it will be a bit safer? Or if you only open the lid a little bit. Still, it’s highly recommended for you to close it after you are done.

Nearly every piano has a fallboard, and you might assume that if it’s there it should be used. Should you close the fallboard on your piano when you’re not playing it?

There are certain instances when the fallboard can be useful to keep people from playing the instrument. If you have a piano in a restaurant or hotel that you don’t want random people playing, you can close the fallboard and the lid and lock the piano (if your piano has a lock). If you have a piano in your home that you don’t want children playing around with this can also be useful.

When it comes to institutional use, the locks on pianos do very little to protect them because they can be easily pried open. That’s why there are much more secure locks available to prevent people from getting inside pianos.

The practical use of fallboards is to prevent dust from collecting on the keys of pianos. And the felts underneath keys Playing a piano with dirty keys feels awful! However, dust will still collect on the fallboard, and you will have to dust the fallboard. With delicate satin finishes, this can be more challenging than dusting the keys.

The biggest issue when it comes to closing the fallboard is whether you have ivory or plastic key tops.

If you have ivory keys on pianos will yellow if not exposed to sunlight on a regular basis. So, closing the fallboard will turn ivory keys yellow over time. In this case, you are better off leaving your fallboard open.

When it comes to plastic keys there are no other benefits to keeping fallboards open unless there is direct sunlight on the keys. Plastic can sometimes react to sunlight and degrade over time. If you want to prevent people from playing your piano or prevent dust from getting on the keys, then closing the fallboard is a good choice. However, it doesn’t prolong the life of your piano or aid its stability.
