Organ
The construction of organs is similar to pipe organs, but the sound of the organs are produced by free reeds. 
By tramping or electricity, one could send the air into organs. Usually there is one layer of keyboards, while some organs compose two layers. Electric bellows would also be added with foot keyboards. There two kinds of reeds in organs, one is pressure and the other is suction. Suction organs are similar to pipe organs in which the players use foot bellows to produce music. Suction organs, on the contrary, sucks the air out from the bellow by trampling the boards. The cases we see on organs are usually made of woods.
Certain famous organists are Buxtehude Pietrich (1637-1707), Johann Sebastian Bach (1685-1750) and Johann Pachelbel (1653-1707).
Famous organ piece: Bach, Toccata and Fugue in d minor.
