Like cars, with use, pianos require periodical servicing. Again, the amount of work required is dependent upon the amount the individual piano is being used. For example, college pianos and pianos owned by professional pianists may be played perhaps ten or twelve hours a day and need regular close attention. In its first few years, servicing will be minimal and will probably need little more than a tune, tone and check over. Then as a piano gets older, more work will be necessary. Again this is dependent on the usage, but it is a simple matter of wear and tear until eventually a piano will need to be rebuilt.
