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. This Spanish trumpet reed stop is of a class mounted en chamade. These stops are mounted horizontally rather than vertically in the front of the organ case, projecting out into the church. As a result they will sound louder than other stops operating on the same wind pressure.
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:
