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 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).

A keyboard instrument is a musical instrument played using a keyboard, a row of levers which are pressed by the fingers. The most common of these are the piano , organ , and various electronic keyboards , including synthesizers and digital pianos .
The break was between middle C and C-sharp, or outside of Iberia between B and C. Broken keyboards reappeared in 1842 with the harmonium, the split occurring at E4/F4. The reverse-colored keys on Hammond organs such as the B3, C3 and A100 are latch-style radio buttons for selecting pre-set sounds.
A hand-pumped Indian harmonium, of the type used in South Asia, here used at a European jazz festival.. The pump organ or reed organ is a type of organ using free-reeds that generates sound as air flows past the free-reeds, the vibrating pieces of thin metal in a frame.
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 criteria for classifying musical instruments vary depending on the point of view, time, and place. The many various approaches examine aspects such as the physical properties of the instrument (shape, construction, material composition, physical state, etc.), the manner in which the instrument is played (plucked, bowed, etc.), the means by which the instrument produces sound, the quality ...
"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]
