I fear that a lot of the skill needed to be a good organist has been lost over the past 20 years or so, one such skill was the ability to adjust ones playing to suit the building & acoustics. Console management, or the lack of it, is partly to blame in my opinion. At a recent recital I attended, the whole program was played on one manual with all registration & manual changes being done with the aid of an assistant pressing the sequencer advance piston. Even the music was on an iPad, with pages being ‘turned’ by a piston!
The management skills of organists like Harry Gabb, for example are now in short supply & sadly missed.
