Tuning
The tuning of pianos, both grand and upright and above all concert pianos, requires a very fine ear, skilled manual skills, knowledge of the construction bases of the sound bodies, of the various strings, perspicacity in grasping the customers' wishes and a large dose of experience. This intervention must be carried out at least once a year, if there are particular needs or the instrument is used frequently; the intervention is carried out at home; if the piano is transported, it is usually necessary to tune it again even if the intervention was carried out recently.
Tuning by ear, guaranteed by a good tuner, is far preferable to tuning carried out using electronic devices.
