The most common of these are the piano, organ, and various electronic keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas , which are struck idiophones operated by a keyboard, and carillons , which are usually housed in bell towers or belfries of churches or municipal buildings.
"Enharmonic keyboard" is a term used by scholars in their studies of enharmonic keyboard instruments (organ, harpsichord, piano, [4] harmonium and synthesizer) with reference to a keyboard with more than 12 keys per octave. Scholarly consensus about the term's precise definition currently has not been established. [citation needed]
Pressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine (acoustic and electric piano, clavichord), plucking a string (harpsichord), causing air to flow through a pipe organ, striking a bell , or activating an electronic circuit (synthesizer, digital piano, electronic keyboard).
Notes in it include a prime symbol below the note's letter. Names of subsequent lower octaves are preceded with "sub". Notes in each include an additional prime symbol below the note's letter. The octave starting at tenor C is called the "small" octave. Notes in it are written as lower case letters, so tenor C itself is written c in Helmholtz ...
What primarily distinguishes the spinet is the angle of its strings: whereas in a full-size harpsichord, the strings are at a 90-degree angle to the keyboard (that is, they are parallel to the player's gaze); and in virginals they are parallel to the keyboard, in a spinet the strings are at an angle of about 30 degrees to the keyboard, going ...
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 basic components of an Indian harmonium include: a wooden body with two metal handles for carrying, banks of brass reeds (often 1, 2, or 3) set on a wooden reed board, a pumping apparatus , air stops (including stops for drones), and a keyboard (which is similar to a piano keyboard but with a smaller number of keys).

The piano action mechanism [1] (also known as the key action mechanism [2] or simply the action) of a piano or other musical keyboard is the mechanical assembly which translates the depression of the keys into rapid motion of a hammer, which creates sound by striking the strings. Action can refer to that of a piano or other musical keyboards ...
