The Pipe organ Portal
The pipe organ is a musical instrument that produces sound by admitting air (wind) through a series of different sized pipes. This process is controlled through the use of keyboards. One of the oldest musical instruments—its origins can be traced back to the Greeks—the organ is capable of sustaining sound for as long as the key is depressed, in contrast to other keyboard instruments, such as the piano and harpsichord.
Pipe organs range in size from portable instruments with only a few dozen pipes to very large organs with tens of thousands of pipes, causing Mozart to describe it as the king of instruments. (more...)
Eight-foot pitch is a term common to the organ and the harpsichord. An organ pipe, or a harpsichord string, designated as eight-foot pitch is sounded at standard, ordinary pitch. For example, the A above middle C in eight-foot pitch would be sounded at 440 Hz. (or at some similar value, depending on how concert pitch was set at the time and place the organ or harpsichord was made).
Eight-foot pitch may be contrasted with four-foot pitch (one octave above the standard), two-foot pitch (two octaves above the standard), and sixteen foot pitch (one octave below the standard). The origin of all these terms is based on the fact that, all else being equal, a pipe or string that is half the length of another will vibrate at a pitch one octave higher. The length "eight feet" is based on the length of an organ pipe sounding the pitch two octaves below middle C.
The organ in Roskilde Cathedral, Copenhagen is an elaborate baroque instrument first built in 1554 by the Dutch organ builder Herman Raphaelis; the façade of the Rückpositiv and the parapet of the gallery stem from this instrument. A thorough rebuild was completed in 1654 which included the installation of the present main façade. The organ was rebuilt to this specification by Marcusson & Son in 1990.

Notable pipe organs
Virgil Keel Fox (May 3, 1912 – October 25, 1980) was a renowned organist, known especially for his flamboyant "Heavy Organ" concerts of the music of Bach. These events appealed to audiences in the 1970s who were more familiar with rock 'n' roll music, and were staged complete with light shows. His style, particularly his taste for fast tempos and flashy registrations, was often criticized for his unconventional interpretations of classical organ music. But on the album "Heavy Organ", in the introduction to the familiar Toccata and Fugue in D minor attributed to Johann Sebastian Bach, Fox summed up his approach to Bach and to music in general:
- "There is current in our land (and several European countries) at this moment a kind of nitpicking worship of historic impotence. They say that Bach must not be interpreted and that he must have no emotion...Pure unadulterated rot!...He has all of this amazing spirit and imagine that you could put all the music on one side of the agenda with his great interpretation and great feeling and put the greatest man of all right up on top of a dusty shelf underneath some glass case in a museum and say that he must not be interpreted!
