In most American organs built twenty years ago, the compass of the pedal board was only two octaves and two notes, from CCC to D. Sometimes two octaves only. Later it was extended to F, 30 notes, which is the compass generally found in England. Following Hope-Jones' lead, all the best builders have now extended their boards to g, 32 notes, this range being called for by some of Bach's organ music and certain pieces of the French school where a melody is played by the right foot and the bass by the left. The chief reason is that g is the top note of the string bass, and is called for in orchestral transcriptions. Henry Willis & Sons have also extended the pedal compass to g in rebuilding the St. George's Hall organ in 1898.
For a long time no means whatever of controlling the Pedal stops and couplers was provided, but in course of time it became the fashion to cause the combination pedals or pistons on the Great organ (and subsequently on the other departments also) to move the Pedal stops and couplers so as to provide a bass suited to the particular combination of stops in use on the manual. This was a crude arrangement and often proved more of a hindrance than of a help to the player. Unfortunately, unprogressive builders are still adhering to this inartistic plan. It frequently leads to a player upsetting his Pedal combination when he has no desire to do so. It becomes impossible to use the combination pedals without disturbing the stops and couplers of the Pedal department.
The great English organist, W. T. Best, in speaking of this, instanced a well-known organ piece, Rinck's "Flute Concerto," which called for quick changes from the Swell to the Great organ and _vice versa_, and said that he knew of no instrument in existence on which it could be properly played. An attempt had been made on the Continent to overcome this difficulty by the use of two pedal-boards, placed at an angle to each other, but it did not meet with success.
The Hope-Jones plan (patented 1889) of providing the combination pedals or pistons with a double touch was a distinct step in advance for it enabled the organist by means of a light touch to move only the manual registers and by means of a very much heavier touch on the combination pedal or piston to operate also his Pedal stops and couplers. Most large organs now built are furnished with a pedal for reversing the position of the Great to Pedal coupler. Though to a certain extent useful when no better means of control is provided, this is but a makeshift.
