Carillon keyboard ranges

The table below summarizes the combined manual and pedal keyboard ranges and configurations of all known traditional carillons around the world.  This may be helpful to composers and arrangers of carillon music who are concerned about how widely their work may be playable and whether to offer alternate note options in the bass.

The eight central columns correspond to the six major countries or regions in which the art of the carillon is concentrated, plus two regions for the rest of the world.  Each of those seven column headings is also a link to the keyboard range index for that particular country or region, making it possible to see not only the details that contributed to the construction of this table but also the available treble ranges which are not considered here.

The instruments are divided into four major groups by total range, as follows:
  Group 1 - grand carillons = at least 4.5 octaves, keyboard G - C (i.e., having extended bass)
  Group 2 - concert carillons = at least 4 octaves, keyboard C - C
  Group 3 - medium carillons = at least 3 octaves, keyboard C - C
  Group 4 - small carillons = less than 3 octaves
Each group is subdivided according to the configuration of the bass end of the playing range that defines the group (which often is less than the total range of the instrument).  The subgroups are identified in the leftmost column and described in the column following the regions and countries.  If "missing or added bass notes" is "(none)" then the instruments in that subgroup are fully chromatic throughout the defining range; there may in fact be additional bass notes below the defining range.  Otherwise, the instruments may be missing one or more bass semitones and/or may have a bass B-flat below the lowest C of the defining range, as defined in this column of the table..  This classification method ignores any additional treble notes above the defining range.

The cells of the table may contain one or two numbers.

  1. When a cell contains only one number, that indicates that all of those carillons have the same keyboard configurations; notable instances are highlighted in green.
  2. When a cell contains two numbers, the first is the number of carillons in that region and subgroup, and the second is the number of different keyboard configurations in those carillons.  The second number may be preceded by "≥", meaning "at least," which indicates that some manual and/or pedal ranges in that subgroup are not fully known.  (Such cells are also highlighted in pink to draw attention to that fact.) 

The numbers of carillons are totalled by subgroup in the rightmost column; both numbers are totalled by country or region in the last row of the table.

Following the table are some observations about differences between regions.

Observations:

1.  The Totals column on the right side of the table does not include counts of the number of different keyboard layouts because that would require a detailed comparison of all individual keyboard range indexes simultaneously, and that effort seems unjustified when so much data is currently missing.

2.  There are so many carillons for which the keyboard ranges are unknown to the compiler of these pages that very few conclusions can presently be drawn with confidence.  Resolving the unknown and partially known configurations (almost a quarter of the total!) will almost certainly make significant changes in many of the numbers in this table.

3.  Nevertheless, these preliminary conclusions can be drawn:
—  Among the grand carillons, by far the most common configurations have only one bass semitone missing.
—  Among the concert carillons, it is equally likely to have one or two bass semitones missing.
—  Among medium and small carillons, by far the most common configurations have two bass semitones missing.
—  There are remarkably few instances where all of the instruments in one subgroup within one region have the same keyboard configuration (both manual and pedal ranges identical).  See the two green highlights in the table.

4.  In spite of all the efforts towards keyboard standardization that have been made by the World Carillon Federation and the various national or regional carillon societies in the last half-century, there are still an astonishing number of different keyboard configurations in existence — far more than can be explained solely by differences in the sizes of instruments (in terms of number of bells).  More than 60 years ago, the realization of this curious situation (in terms of the carillons that then existed) prompted the initial collection of this type of information, which now forms the central core of this Website.  That this curious situation remains true today demonstrates clearly that what was then an important reason remains today an important reason for continuing this Website as a public service.
