What is the Piano Guard System

Piano Guard System is a system that literally guards the maintenance of the instrument in the best possible condition.

Taking care of the value of the instrument provides it with the right climate and environment in which it should be.

Without the right conditions in which the instrument should be used, it can unfortunately lose its aesthetic qualities, but also its sound qualities - which every user cares about the most.

See how it works

Under what conditions should the instrument be used?

Such a climate, is provided by the Piano Guard System, or literally Piano Guard, which protects the piano from unstable microclimates by controlling the instrument's environment and responding to changes in it.

Humidity level

45% - 60%



+/- 2°C

It is advisable to set the instrument away from any kind of heat source (radiators, fireplaces, sunny windows, or those opened when it rains)

Ensure ideal conditions

To protect your instrument and preserve its aesthetic and functional qualities, use the Piano Guard System. Enjoy the excellent sound quality of your instrument!

What's the harm to our instruments at home, in the hall or on stage?

Based on the recommended storage conditions of the instrument, there are a number of risks that we do not pay attention to. However, for the instrument, they can have a very adverse effect:

High humidity

Indoor humidity exceeding 60%. Areas close to nature (forests, seas, lakes, meadows) are particularly vulnerable.

Low humidity

Humidity in the room below 45%.
Such a value is most often found in cities.

Rapid changes in conditions

Too rapidly changing environmental conditions through frequent opening of doors, windows.

Distance from heat sources

Too little distance between the instrument and any type of heat source such as radiators, fireplaces or underfloor heating.
What happens to an instrument deprived of a suitable environment?
Pianos or pianos are actually works of art consisting of more than 11,000 parts with not easy to maintain structure, and we are talking about: wood, iron, steel, metal, brass, felt materials, cashmere, etc.
Each of the plastics in the instrument is extremely interconnected and needs the right conditions to fully fulfill its most important role - pleasant and harmonious playing of the instrument.

Each of these parts, however, is incredibly affected by the unfriendly climate in which it is located, and this powerfully affects the performance and longevity of both these parts and the instrument as a whole.
Wood, i.e. the entire body of the instrument, its resonant bottom, tuning bar, bass and treble bridge, keyboard and other smaller components
Cast iron frame, or the soul of the instrument
Steel, or bass and violin strings
Brass, i.e. elements of the mechanism, acoustic part and instrument case
Cashmere and felt materials, or elements of the acoustic party
Impact of adverse environment on instrument components
What happens when we leave our instrument in unfavorable conditions? Unfortunately, but an avalanche of undesirable actions follows.


In favorable conditions, the bottom of the instrument is resilient , and its elevation properly reflects any sound transmitted through the bridges from the strings. However, if the soundboard suffers the effects of excessive moisture, it unfortunately begins to swell, which ultimately leads to an unpleasantly harsh and high sound coming out of the instrument. When the environment in which the instrument is placed is too dry, the soundboard deforms, flattens and eventually cracks along the grain, with the sounds becoming very muffled often even deaf.


Pinblock is responsible for maintaining the instrument's tuning, but an unsuitable environment the material tends to crack. The tuning pins cease to play their role. A cracked pinblock involves the inability to properly tune the instrument. Unfortunately, a cracked pinblock involves replacing it with a new one.

Iron frame

The soul of the piano. The largest cast-iron component of a piano or grand piano, which, despite its sublime beauty, plays an extremely important role of maintaining the enormous string tension ranging from 15-20 tons in a grandpiano, and up to 12 tons in a piano. Its corrosion, caused by really unfavorable environmental conditions can lead to cracks in the most sensitive areas.

Bass and treble bridge

The bridges efficiently and deftly locate each sound on the soundboard. However, if they experience unfavorable environmental conditions, they begin to crack, which ultimately results in the loosening of the overlay pins, thus losing string stability and the unwanted string buzzing sound.

Mechanism and keyboard

That is, the extremely complex center of the instrument, which is made up of all the possible materials mentioned above. Here, the moisture or dryness also makes its presence known. One may feel the rasps while playing or experience the looseness while playing and the complete unsettling of the mechanism, felt and heard every time the key is struck.

Bass and violin strings

Strings, also known as the sound generator of the piano - unfortunately, the unregulated environment in which they are placed, makes these begin to undergo the process of corrosion, rusting and often breaking off. They cannot fulfill their proper role.

Tuning pins, screws

If not maintained in proper conditions, they will rust, deform and fail to serve their purpose. Deformed tuning pins and bolts should be replaced with new ones.
Reading the listed potential damages, it is clear that the unfavorable environmental conditions in which the instrument is used will lead to unpleasant playing on it, and ultimately to the need for costly renovation. The instrument will not maintain proper tuning and tonality. Fortunately, it is possible to prevent all the aforementioned situations and certainly the undesirable effects of an immoderate environment. The answer is to install a device in your instrument that is capable of maintaining a proper microclimate.

Piano Guard System, despite the often unfavorable conditions that prevail in the environment where the piano or grand piano is placed, is able to maintain the appropriate microclimate, which prolongs the life and efficiency of all parts of the instrument. Thanks to Piano Guard System, the user can be rest assured about the condition of his/her instrument and maintenance of stability of the conditions in which it should be placed. Piano Guard System constantly informs the user about the level of humidity, temperature measurement, reminds about the needs of adding water for humidification and changing the cellulose pad for drying the climate. The Piano Guard System is a device that not only follows specific rules for taking care of the instrument, but is also responsible for keeping the user informed of what is needed at any given time. The user, thanks to both a mobile application and a web application available at, is able to track the microclimate of a given instrument, or multiple instruments if the user has a larger number.

Take care of your instrument

To protect your instrument and preserve its aesthetic and functional qualities, use the Piano Guard System. Enjoy the excellent sound quality of your instrument!
