Kasper (kaspervdpol)

If we play Bach on an old and well-preserved Silbermann organ, both players and hearers are as little conscious as the master himself was of the need for frequent changes of register, for on such an instrument the diapasons and mixtures gave a forte so rich, intense, full-coloured, and yet in no wise fatiguing, that we can, if need be, preserve it unchanged throughout a prelude or a fugue.
