The Railsback curve shows how a piano tuned to compensate for inharmonicity deviates from theoretically correct equal-tempered tuning. The Railsback curve, first measured in the 1930s by O.L. Railsback, a US college physics teacher, expresses the difference between inharmonicity-aware stretched piano tuning, and theoretically correct equal-tempered tuning in which the frequencies of successive ...
Stretched tuning is a detail of musical tuning, applied to wire-stringed musical instruments, older, non-digital electric pianos (such as the Fender Rhodes piano and Wurlitzer electric piano), and some sample-based synthesizers based on these instruments, to accommodate the natural inharmonicity of their vibrating elements.
The normal 88 keys were numbered 1–88, with the extra low keys numbered 89–97 and the extra high keys numbered 98–108. A 108-key piano that extends from C 0 to B 8 was first built in 2018 by Stuart & Sons. [4] (Note: these piano key numbers 1-108 are not the n keys in the equations or the table.)
It is standardized by the International Organization for Standardization as ISO 16. While other frequencies have been (and occasionally still are) used to tune the first A above middle C, A440 is now commonly used as a reference frequency to calibrate acoustic equipment and to tune pianos , violins , and other musical instruments .
Musical acoustics or music acoustics is a multidisciplinary field that combines knowledge from physics, [1] [2] [3] psychophysics, [4] organology [5] (classification of the instruments), physiology, [6] music theory, [7] ethnomusicology, [8] signal processing and instrument building, [9] among other disciplines.

In fact, until this past weekend, Kate hadn't worn her engagement ring in any public appearance—or any images or videos shared on Kensington Palace's social media channels—since attending the ...
Piano tuning is a compromise—both in terms of choosing a temperament to minimize out-of-tuneness in the intervals and chords that will be played, and in terms of dealing with inharmonicity. For more information, see Piano acoustics and Piano tuning.
