The Art of Tuning…
Piano technicians are highly skilled artisans in all phases of piano work through years of practice, study and experience...
For those in search of more detailed informations regarding Tuning and Repairs on pianos...here they are down below...
First of all, piano tuning does not last forever. In my experience, there are 3 main contributing factors to a piano going out of tune:
1) Seasonal changes (effects of temperature & humidity)
2) Style & frequency of Playing
3) General wear & tear over time (In brief, the older the piano = more sensitive, whimsical & fastidious)
First you must understand how a piano works. The vibrating string, which produces the sound, is held under tension between the [tuning pin] and at the other end on the metal harp (the iron frame). On a typical piano the total amount of tension can reach up to 20 tons. (comparatively, a guitar hold about one ton of pressure on its neck).
Now, if you want to know more about why a piano, like most tempered instruments (saxophone, guitar, trumpet etc.) need to be slightly out of tune, in a calculated way, so that the purely musical ear can make sense out of it, you can read more on this subject in the sub-menu called [TEMPERAMENT].
You can also learn, in another sub-menu, about other adjustments necessary to match the natural [INHARMONICITY] of your piano.
In the section Repairs, you may look on 3 topics:
Action regulating is the basic mechanical adjustments pianos are often needed.
Where we talk about the impairment of a piano tone due to worn hammers and how to remedy it.
3) ‘Other Repairs’
Talks about the other things that can be fixed on a piano: from restringing to simply fixing sticky keys.
