Here is an example of that large a piano (and yes, we're all jealous): To fit low bass strings inside a typical piano, they are wound with thicker wire which makes the pitch lower but makes the tuning and timbre of the tuning different, and that means that the smaller the piano, the less in tune it can be or the greater inharmonicity it will have. The only way to totally prevent inharmonicity is to build a piano of 30 or more feet in length. In addition to having multiple tunings of strings together in one keystrike, any piano-including the largest instruments in regular manufacture-have 'inharmonicity' built into them, which means that no amount of tuning will make the top and bottom notes of the piano perfectly in tune with each other. To get more of an American sound in Pianoteq rather than the European sound, set Unison Width to '1' and Octave Stretching to (roughly) '1.13' or up to '1.25' (on smaller instruments). European technicians tend to add more unison width (and less octave stretching) than American technicians, because of how European pianos and built and what audiences and soloists prefer in Europe. Here is a chart and paragraph that explains this in much greater detail and may reflect the out-of-tune notes you're hearing: Īlso, most keys on a piano strike multiple strings (bichords and trichords and-very rarely on a few pianos by Borgato-tetrachords), and each part of the 'unison' or group of strings will be tuned slightly differently to help make even more intervals consonant and referred to as unison width.

Most technicians will use hardware specifically programmed with those slight changes to tune for some strings when servicing an instrument. While modern piano tuning is much closer to a true equal temperament than historical tuning, it isn't exact in the way that other instruments are tuned to be exact. In practice there is no real 'equal temperament' for piano like there is for instruments-especially the organ, because of how they're designed and built, each note is slightly off of equal temperament to keep intervals-especially octaves-as 'consonant' as possible.

Does your app show which keys are out of tune and by how much? (The best indicator is in 'cents' for piano tuning.)
