crescendo pedal

In addition, an organ may have a crescendo pedal, which would be found to the right of any expression pedals, and similarly balanced.

This gives the device a much longer field of operation than the modern crescendo pedal, thus making the dynamic change more smooth and gradual.

An organ may also have a similar-looking crescendo pedal, found alongside any expression pedals.

The crescendo pedal is located directly above the pedalboard, to the right of any expression pedals that may be present.

On pipe organs, the expression pedal should not be confused with the crescendo pedal, which progressively adds stops as it is opened.

The crescendo pedal is typically used only in certain repertoire, and, generally speaking, the organ's expression pedal(s) are more commonly used.

Reed organs and harmoniums of the late 19th and early 20th centuries often had a similar mechanism to a crescendo pedal.

An electrically-operated crescendo pedal resembling an expression pedal was invented and mounted to the right of the expression pedals.

The order in which the stops were activated by the crescendo pedal was set by the organ builder and could not be modified by the organist.

The crescendo pedal incrementally activates stops as it is pressed forward and removes stops as it is depressed backward.

Often an indicator light or lights will be present on the console to inform the organist of when the crescendo pedal is activated and how far it is engaged.

As a result, in organs with these devices, the stops controlled by the crescendo pedal are usually customizable, as is the order in which they are activated.

Pressing the crescendo pedal forward cumulatively activates the stops of the organ, starting with the softest and ending with the loudest; pressing it backwards reverses this process.

A crescendo pedal is a large pedal commonly found on medium-sized and larger pipe organs (as well as digital organs), either partially or fully recessed within the organ console.

In 1986, the electrics were renewed and although the Willis console was retained, it was given a solid state action with eight memory levels for the combination pistons and four for the Crescendo pedal.

Applying the crescendo pedal will incrementally activate the majority of the stops in the organ, starting with the softest stops and ending with the loudest, excluding only a handful of specialized stops that serve no purpose in a full ensemble.

In 1967, Olivier Messiaen, well along in his career as organist at the Eglise de la Sainte Trinite in Paris, took custody of a newly rebuilt instrument with a crescendo pedal, an electrified action and other technological enhancements.

Usually this was called a 'full organ pedal', as it did not gradually engage ranks of stops in the manner of a true crescendo pedal, but simply engaged all the stops (and usually any octave couplers fitted to the instrument) when operated, with no progressive action.

When feeling for a pedal while playing, the organist should remember that the crescendo pedal is normally the right-most of the volume pedals, and that its surface is often raised slightly above the expression pedal(s) so as to help the organist to avoid selecting it by mistake.

It has 1,235 stop tabs controlling 587 flue stops, 265 reed stops, 35 melodic percussions, 46 non-melodic percussions, 164 couplers, 18 tremolos, 120 swell pedal selectors for the 6 swell pedals controlling 15 swell boxes, and a stop crescendo pedal.

The order in which the stops are activated is usually preset by the organ builder and the crescendo pedal serves as a quick way for the organist to get to a registration that will sound attractive at a given volume without choosing a particular registration, or simply to get to full organ.

Because the crescendo pedal both resembles and is adjacent to the expression pedal(s), it may confuse beginning organists, such as pianists who are filling in at the church organ, who intend to use the expression pedal(s) rather than the crescendo pedal.
