The piano section is the main axis of our shop.

Today, Josep Audenis Prat embodies the fourth generation dedicated to this instrument. He began learning with his father and subsequently expanded his professional training at the Euterpe and Schimmel piano factories in Germany. He eventually obtained certification at the Steinway Academy in Hamburg which accredits him as one of the best piano tuning specialists and technicians in our country.

A healthy piano gradually detunes and tones around 1 Hz in a year. If this descent accumulates the piano besides detuning it will be low in tone. When the entire piano is adjusted again, it will have to be adapted to the change of tensions of the strings:
Each string has an average of 70 to 100 kilos of tension (the most serious boards reach 200 kg), which together give between 15 and 20 tons that must withstand the headstock, harp and harmonic board (in addition the strings make a force of about 360 kg on the bridge, and this on the harmonic board). If you raise the tension of all the strings of a piano, the weight change is very important and needs days to adapt and distribute the tension, this adaptation entails a detuning.
As the structure of the piano (the metal harp and harmonic board) have some elasticity, in addition to the elasticity of the steel strings themselves and the twisting of the pegs, when the tone is raised to the piano, the structure, strings and piano pegs move and modify the tensions of the strings as they are tuned, and also in the days following the tuning , making tuning unstable and making the piano need more than one tuning.
The process of elastic deformation of the piano structure, strings and pegs is not only immediate. That's why sometimes you can't turn up the piano tone and tune, you have to re-tune the piano another day.
The pitch ups also carry a risk of breaking some string, the higher the pitch rise and the older the strings have the greater the chance of breakage there is.

There are pianos that need regular tunings:
• Pianos that have a lot of use like those of music schools.
• Pianos with special requirements such as concert or recording rooms.
• New pianos should be tuned the same year because they lower pitch earlier because they are still adapting to the tensions of the strings and the humidity of the house.
• Pianos that have been moved should be tuned after transfer, when the piano woods have adapted to the humidity of the new house.
• Pianos located in places with large changes in humidity, as well as pianos located near air conditioners or radiators, with incidence of the sun or air currents, are challenged earlier. That is why it is important as far as possible to place the piano in places with adequate conditions: away from windows, preferably away from walls that give to the outside, away from radiators and away from the current of the air conditioning.
