 in Northern Germany. This took the form of a vertical style of registration in which ensembles were ideally built up with no pitch being duplicated in the same octave. The movement endorsed the so-called Werkprinzip, in which each division was based on a principal-scale rank of a different octave.

Organ voicers strove for an articulate speech characterized by chiff and avoided nicking, beards and other means of achieving 'smoothness'. Low wind pressures were revived. Casework was often eschewed in favor of open standing pipework and swellboxes became relatively rare.

In Europe the movement was indelibly connected with mechanical action instruments; in North America this was not the case and many instruments characteristic of the Organ Reform Movement had electric action.

Some of the leading builders of the movement were Frobenius
