Since the piano must be maintained at a specific tension to achieve a good musical sound, the matter of maintenance becomes an on-going process. Since a piano consists mainly of wood and iron, all of this is subject to movement. The movement of the wooden sound board, framework, cause the wires to change tension without prompting by the user. Thus, it becomes necessary to set up a minimal schedule of
tuning of the instrument to ensure reliable and pleasant results. Of course, this schedule can't be, nor is it a hard and fast one. But, we can make recommendations and set out guidelines. You should evaluate your piano usage in terms of your own experience.
