Vox Humana Posted January 22, 2006 Share Posted January 22, 2006 I feel embarrassed at having to ask this, but I'm a bit out of touch and not a little confused. When I was a kid the system used almost universally in Britain to describe the pitch of organ pipes was a variant of the one used by Robert Smith in his Harmonics (1748). The lowest note of a 16' open pipe was CCC, an 8' pipe CC and the subsequent octaves were C, c, c' c'' etc. And I seem to remember that when the system was used to describe manual and pedal compasses, the bottom key on the manuals was CC called, but the lowest pedal key was CCC. These days I get the impression that this has been superseded by a variant of the Helmholtz system which effectively moves everything up an octave so that a 16' pipe is now CC. And there is no longer any octave difference between the manuals and pedals: the lowest key of each is C. But am I right in thinking that this latter system (which has been endorsed by some influential people including Peter Williams, Stephen Bicknell and NPOR) is now usual? Which system do you use? And do you recognise an octave differential between the manuals and pedals? Link to comment Share on other sites More sharing options...
