Cross-stringing (sometimes called overstringing) is a method of arranging piano strings inside the case of a piano so that the strings are placed in a vertically overlapping slanted arrangement, with two heights of bridges on the soundboard instead of just one.
Though moving a piano may seem like a simple procedure, there are hidden factors which compound the procedure. Pianos are difficult to move and should only be moved by a professional who is careful, properly trained, insured, and has the proper equipment. An upright piano is the most popular and simpler to move than a grand piano.
[6]: 88 The 2000s-era grand piano action is a distant descendant of Cristofori's original. One of the most well-known French piano actions was created by Jean Schwander in 1844 and improved upon by his son-in-law Josef Herrburger; the Schwander action is still used in Bechstein pianos. At the turn of the century, Schwander-Herrburger merged ...

A transposing piano is a special piano with a mechanism (operated by a pedal or lever) that changes the keyboard position relative to the action (see Development of the modern piano for details). This transposes (changes the key of) any particular keyboard fingering.
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 ...
Target space is a subspace of free space which denotes where we want the robot to move to. In global motion planning, target space is observable by the robot's sensors. However, in local motion planning, the robot cannot observe the target space in some states.

String piano is a term coined by American composer-theorist Henry Cowell (1897–1965) to collectively describe pianistic extended techniques in which sound is produced by direct manipulation of the strings, instead of or in addition to striking the piano's keys.
