What is an Organ?

The organ as we know it developed from a group of individual organs brought together into one place to be played by one person. Each of these organs as its own character and volume controlled from its own keyboard. This allows for the use of contrasting sounds; they can also be joined together to give a bigger sound. The sound is produced by wind/air being blown into a pipe. They come in two (2) main types: flue  and reeds.

Flue

These come in three (3) groups: foundation, flutes and strings.

Foundation

The main sound on the organ and does not resemble any other musical instrument.

Flutes

Pure, clear toned, a sound close to the flutes of the orchestra or the recorder etc. Used in contrast to the foundations or for solos.

Strings

Luscious, sensual, bright and warm sound can be made imitate orchestral string

Reeds

Sound made by vibrating metal reed, can be a quiet stop (oboe) up to very-very loud (Fanfare Trompette) for solos or made to blend with the foundations (Cornopean)

Types of action

Pneumatic Action (exhaust) The action is shown in the ‘off’ position. The windchest [A] and the primary action box (B) are filled with air under pressure.
