Much of a piano is made of wood and is therefore extremely sensitive to fluctuations in humidity. The piano's wooden soundboard is designed to have an arch, or crown. The crown increases or decreases with changes of humidity, changing the tension on the strings and throwing the instrument out of tune.
Similar to the membranes used on membranophones, the strings that are used on chordophones may need to be replaced if an instrument is to be performed with. A conservator will need to examine the structure of the instrument to see if stress cracks from the tension of the strings have begun to develop. Musical Bows; Harps; Lyres; Lutes; Zithers
Aliquot stringing is the use of extra, un-struck strings in a piano for the purpose of enriching the tone. Aliquot systems use an additional (hence fourth) string in each note of the top three piano octaves. This string is positioned slightly above the other three strings so that it is not struck by the hammer.
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 ...
The lack of a soundboard means that vibration from transport and humidity is unlikely to change the sound. [7] Because the CP-70 uses custom-made strings, sourcing new ones can be problematic. Each iteration of the instrument used a different type of string, although some of the treble strings can be replaced with standard ones from an acoustic ...
Aliquot stringing is the use of extra unstruck strings in the piano for the purpose of enriching the tone. The aliquot stringing system was invented by Julius Blüthner in 1873. As currently implemented, the Blüthner aliquot stringing system uses a fourth string in each note of the top three octaves. This string is raised slightly with respect ...
