• Other Families of Stops

o Percussion

The Percussion family includes voices such as the Chimes, Handbells, Harp,

Celesta and Harpsichord. These stops have a percussive attack and gradually

grow softer as you hold the note. The Zimbelstern is also a member of the

Percussion family.

o Orchestral

Examples of Orchestral voices include the Strings, Slow Strings, Orchestral Oboe

and Brass Ensemble.

o Choral

Examples of Choral voices include the Soprano Ah, SATB Ah, SATB Oo, Boychoir,

and Amens/Alleluias.

• The number on the stop shows its pitch.

The stops and couplers on the organ each have a pitch designation listed in feet (8’, 4’, 16’,

etc.). 8’ refers to concert pitch; a key played on an 8’ stop will have an identical pitch as the

same key played on a piano. 16’ represents an octave below concert pitch; a key played on a

16’ stop will sound an octave below an 8’ stop. This system of designating pitches represents

the approximate length of open organ pipes; the largest pipe in an 8’ rank is approximately

eight feet long; the largest pipe in a 16’ rank is about sixteen feet long. Other footages and

their relationship to concert pitch are listed in the table below:

Pitch Relationship to concert pitch

32’ two octaves below

16’ one octave below

8’ equal to concert pitch (also known as ‘Unison’)

4’ one octave above

2’ two octaves above

1’ three octaves above

• Fraction? It’s a “Mutation” stop.

Mutation stops have fractions in their pitch designations. This means that their pitch falls

somewhere other than on the octave. (Refer to the table below).
