Why are no two pianos tuning the same?

Scale design is different across brands and models. The inharmonicity inherent in the design does not play a large factor in the midrange, but it can have an effect on the technician's choice of stretch, which can. Not every technician tunes equal temperament, for both good and trivial reasons, depending.

Are all pianos tuned to same pitch?

Pianos are usually tuned to a modified version of the system called equal temperament. ... In all systems of tuning, every pitch may be derived from its relationship to a chosen fixed pitch, which is usually A440 (440 Hz), the note A above middle C.

Can a piano be tuned differently?

Unlike guitars or violins where there is an established standard for how each string should be tuned, pianos are all tuned differently. This means that if you were to compare two freshly tuned pianos the notes would not match, even though each piano sounds in tune with itself.

Why are pianos impossible to tune?

But that doesn't work for the piano, and this is why: it has too many strings. It has a string for all of the 12 semitones for the western scale, each attached to a different key. ... But the short version is that it's mathematically impossible to tune a piano across all keys using harmonics.

Why are pianos tuned to 440?

If you have ever gone to a concert and heard all the musicians tuning their instruments to pitch, they were tuning it to A-440. ... This tension is achieved by tightening the strings and bringing them up to concert pitch. The tension maintains the correct shape of the soundboard and gives the piano more carrying power.
