How Does an Organ Works

An organ is a type of musical instrument. It produces sound through blowing of wind into metal or wood pipes. These pipes are usually held in place by racks which are positioned on the top of chests. Chest is that kind of airtight box which features leather valves sample in size inside it and it is the one which allows wind to get into the pipes once the operator presses console keys. This wind originates from centrifugal blower small in size which is driven by a motor mostly run by electricity. The wind passes after regulation of wind pressure which is done by the reservoir or the bellows. The wind lines then direct towards the chest that wind which is in the reservoir.

 

As per definition which is given for an organ, it must contain some specific components which take different forms. For the past years, organs have grown and gained other special features which make them quite different. The mechanical complexity, size and appearance of an organ has greatly changed since its introduction in the BCE second century. The musical aesthetics of the instrument has also changed technologically. However, there are features if not present in an organ the instrument changes to be called an organ. Such features include:

 

The number and specific nature of pipes.

The devices responsible for changing the timbres.

The devices responsible for changing dynamics

The placement and appearance of components

The present number of keyboards.

 

The number of pipes in an organ determines the number of keys the organ will have. Each key has one pipe with the different pipes bring out the same quality of the tone though very different pitch. The key named number one opens valve below the longest pipe which also produces a very low note of all. The other successive pipes tend to be shorter and also produce notes quite higher.

 

The simplest known organ is characterized of a single pipes rank and is able to produce a single tone color. So as to produce varied color, you require another pipes rank of varied shape. An organ then features 2 stop controls which the person operating the organ can operate to make a choice between which of the two ranks to use. To increase available sound, you only need to as more pipes’ rank with their stop controls in correspondence.

 

The organ also features manual keys. These are to be operated by the hand. The feet also have pedal keys to operate. The feet are responsible for playing baseline that simply implies low notes. The long pipes are the ones which bring out low notes. However, you can also use the pedal to play higher-pitched memories using the ranks having shorter pipes.

 

For organs which have mechanical linkage connection between its chests and the keys, the organ usually has the tracker action. For organs whose connections are electric but of low-voltage circuits connected to magnets, that organ is said to have electric action. Also if the connected magnets use pneumatic motors small in size to operate and ones which open valves directing to pipes, that type of organ is said to have electromagnetic action.
