Organ Dictionary

Pedal/Pedalwerk/Pedal: The keyboard you play with your feet. Full compass for pedal is 32 notes but this organ will have only 25. Unison pitch for a pedal stop is 16′.

Bourdon/Bordun/Bourdon: A stopped wooden flute of large scale. It’s intended to give a buzzing, resonant tone. 16′ in the pedals, 8′ in the manuals. It’s considered an essential pedal stop. In this organ, it provides the 16′ foundation tone.

Lieblich Geſchallt/Lieblichgeſchallt/Lieblich Geſchallt: A small-scaled 8′ covered flute with a very soft tone. This organ will have one made of wood instead of the more proper metal and it will serve as an alternative Echo foundational for the pedal division.

Violoncello/Violoncello/Violincello: A full-toned string stop immitative of the orchestral cello. It gives a rich, deep tone and is usually found at 8′ in both the manual and pedal. Will provide the string foundation for this organ.

Lieblich Flute/Lieblichflöte/Lieblich Flute: Intended to be a medium- scaled 4′ covered flute with a very soft tone. This organ deviates from spec by narrowing the scale down to match the Lieblich Geſchallt which it extends. It will provide soft-spoken pedal undertones for more rounded flute solos.

Swell/Schwellwerk/Swell: The second manual. The division is often enclosed within a swell box which is fitted with vertical louvers that can be opened or closed along a continuum with either (or both) a crescendo pedal and/or a balanced expression pedal.  Unison pitch is 8′.

Geigen Principal/Geigenprinzipal/Violin Diapason: A stringy-sounding diapason that does not attempt to imitate any other instrument but provides a welcome backing for a diapason or string chorus or solo expressiveness when backed with low, resonant flutes.  A very versatile stop found at 8′ in the manual or pedal.

Rohr Flute/Rohrflöte/Chimney Flute: A partially-stopped flute of wide scale whose cover or stopper has a hole bored through it and a chimney attached. Since this organ is 100% wood pipes, this Rohr Flute will be identical to any other stopped flute of similar scale, except that above Tenor C (4′), the stoppers will have holes bored through them.

Provides a very liquid-sounding tone that speaks very well as a flute solo backed with a low, quiet bass. May be found at 16′, 8′, 4′, or 2′ in any division. The octaves below tenor C will be borrowed from the Gedeckt rank in the Great division.

Geigen Octave/Geigenoktav/Violin Diapason: A Geigen at octave pitch. See Geigen Principal.

Gemshorn/Gemshorn/Gemshorn: In its original form, a conical metal flute that provides a hybrid tone consisting of flute, string, and horn elements with an emphasis on the string found at 32′, 16′ 8′, or 4′ pitch in any division. In this organ, the gemshorn will be made of wood and so will be closer to a pyramid diapason but with a flute voicing.

Nacht Horn/Nachthorn/Night Horn: A very wide open flute stop with a soft voice. It’s intended to give a haunting, eerie solo flute voice in either the manual or pedal. It is most often found at 4′ and 2′ pitch.

Nazard/Naſat/Nasard: A mutation flute stop that provides the twelfth harmonic of the fundamental (2 2/3′ in the manuals, 5 1/3′ in the pedals). It’s stopped in the bass octaves and open in the treble. When in the Great or Pedal divisions, it has a wide scale. When in the Swell, it has a narrow scale.

Block Flute/Blockflöte/Block Flute: A large scale open flute stop originally imitative of a recorder. May be found at 32′, 16′, 8′, 4′, 2′, or 1′ pitch in any division. In this organ it will be scaled to match the Nacht Horn, which it extends.

Flautino/Flautino/Flautino: A 2′ open flute stop of medium scale and moderate voice found in the manuals.

Larigot/Sifflöte/Larigot: A mutation flute stop that provides the nineteenth harmonic of the fundamental (1 1/3′). Found only in manual divisions, usually in the Swell. On this organ, it has only 56 notes due to physical size limitations of constructing wooden pipes.

Great/Hauptwerk/Great: The main manual division of an organ, intended to provide the primary tones of the instrument.  Unison pitch is 8′.

Gedeckt/Gedeckt/Gedeckt: A covered flute of 32′, 16′, 8′, or 4′ pitch. May be found in any division. Provides a smooth, round, liquid voice that, in this organ, serves as an alternative foundation voice in the Great division. The lowest two octaves will be enclosed to provide the lowest two octaves of the Rohr Flute in the Swell division.

Principal/Prinzipal/Diapason: The fundamental stop of an organ. An open diapason at 8′ pitch in the Great division. It has a medium scale and provides the foundation for the organ.

Octave/Oktav/Diapason: An open diapason of 4′ pitch found in the Great division. Provides the octave pitch of the fundamental.

Twelfth/Quint/Octave Quint: A mutation diapason that speaks the twelfth harmonic of the fundamental (2 2/3′ in the manuals and 5 1/3′ in the pedal). Of smaller scale than the Octave diapason. Usually in the Great or Pedal divisions.

Super Octave/Superoktav/Diapason: An open diapason of 2′ pitch found in the Great division.

Wald Flute/Waldflöte/Wood Flute: A large-scale flute with a strong, hollow tone found at 2′ pitch, usually in Swell or

Choir divisions. In this organ, provides a solo flute voice in the Great intended to complement the Gedeckt series as an alternate foundational voicing.

Nineteenth/Quint/Nineteenth: A mutation diapason that speaks the nineteenth harmonic of the fundamental (1 1/3′). It is usually found in the Great manual. In this organ, limited to 56 notes due to physical size restrictions of wooden pipes.

Choir/Rückpoſititiv/Choir: The third manual of an organ, intended to support (or replace) the choir in a church. Often contains solo stops that imitate the human vocal range and timbre. In this organ, it’s the name given to the partial-compass floating division that can be physically detached from the console. Unison pitch is 8′.

Octave Viola//Octave Viola: A 4′ string stop intended to imitate the orchestral viola. Used as the string solo stop in this organ.

Octavin/Oktavin/Octavin: A 2′ harmonic flute intended to replace the Superoctave with something more complex-sounding than a diapason. Used as the vocal solo stop in this organ. Only the top 44 pipes will be of 4′ length and overblown to speak the octave, the rest will be of 2′ unison length and pitch.
