Musical Instruments - The Keyboard

There are many kinds of musical keyboards, from the accordion to player pianos. It is traditionally defined as a set of adjacent levers or keys that can be depressed to create a sound. A properly built keyboard can traditionally represent the twelve notes on the musical scale, with smaller keys for octave intervals.
Sound is created on a keyboard is created when the key is depressed, which leads to a string being struck or plucked, air going through a pipe or a bell being struck. The most commonly encountered keyboard instrument is the piano, which has led to the layout being called the 'piano keyboard'.
Accordion
The accordion is a kind of musical instrument that hails from Europe. Likely made popular in North America by Weird Al Yankovic, it produces an extremely distinct sound, one that is not likely to be mistaken for anything else. Due to the way that it is operated, it is often called a "squeezebox".
Most models of accordions are diatonic, which means that they produce a different sound depending on whether or not air is entering or exiting the instrument.
Playing the accordion requires more dexterity than the average keyboard instrument. It requires the user to 'pump' or 'squeeze' the instrument as they are playing the accordion, with both hands controlling either side of the accordion. It is, however, extremely rewarding and unique as an instrument.
The Harpsichord
Like the accordion, it is a European keyboard instrument. It makes its sound by plucking the string rather than striking it the way a piano would. Otherwise, it is extremely similar to a piano in terms of looks. However, it only looks like a piano. It sounds completely different.
This keyboard was most widely used during the Renaissance and is best used in Baroque music. While use of this instrument waned after the age of rebirth, it found new life in the twentieth-century, coming back into style in pop culture through new musical compositions.
The Organ
The organ is an ancient style of piano which uses air power as opposed to striking a string like a normal piano would. When an organ player presses a key, it completes a circuit that releases air through a pipe, generating a sound. This gives it the ability to sustain a note, something that a normal piano cannot do.
Unlike a piano, which is made to lead an arrangement, organs are traditionally delegated as the body of a musical piece. It can give a lot of depth to an arrangement as it can sustain a note indefinitely. Most of the time, its part is to offer support to the rest of the piece.
