Organ reform movement

Concert organist E. Power Biggs was a leading popularizer of the movement in the United States, through his many recordings and radio broadcasts.

The movement ultimately went beyond the "Neo-Baroque" copying of old instruments to endorse a new philosophy of organ building, "more Neo than Baroque".

The movement endorsed the so-called Werkprinzip, in which each division of the instrument's pipework was based on a principal-scale rank of a different octave.

In North America this was less emphatic, and many US and Canadian instruments characteristic of the Organ Reform Movement had electro-pneumatic or direct electric action.
