Well I am not a manufacturer but when I think about it it should be logical. A higher sharp is uncomfortable and a lower sharp too. Besides, a lower sharp would make your fingers touch the whites, just like when there is too little paper punching under the sharp. I remember playing on several pianofortes and harpsichords which had the weirdest (in comparison with modern keyboards) whites and sharps. Some felt ok but others were strangely narrow or low. So I suppose 12 mm for sharps is an accepted and comfortable height and high enough to make a proper key dip without touching the white keys. friendly greetings from Antares, Amsterdam, Holland "where music is, no harm can be" visit my website at : http://www.concertpianoservice.nl/ > From: Avery Todd <avery@ev1.net> > Reply-To: Pianotech <pianotech@ptg.org> > Date: Fri, 18 Oct 2002 15:23:28 -0500 > To: Pianotech <pianotech@ptg.org> > Subject: Re: key dip, dip in..... > > Andre, > > Why? > >> Most manufacturers use 12 mm for the sharps. >> >> >> friendly greetings >> from >> >> Antares, >> >> Amsterdam, Holland >> >> "where music is, no harm can be" >> >> visit my website at : http://www.concertpianoservice.nl/ >> >> _______________________________________________ >> pianotech list info: https://www.moypiano.com/resources/#archives > > > _______________________________________________ > pianotech list info: https://www.moypiano.com/resources/#archives >
