The humidity in the room where the piano is installed is important. It should be between 40 and 60%. A favourable room temperature is about 20° C. At higher temperatures the air becomes drier and requires additional humidification, for example by a humidifier.
The maintenance of the instrument also includes tuning it 1-2 times a year by an authorised specialist. If a piano is played very intensively, more frequent tuning may be necessary.
The piano action is subject to constant wear and tear even under normal, non-intensive use. As a result, a piano action service is required at least every 4 to 5 years.
