Key height adjustment (on a modern instrument with key frame bolts) can be done in 2 minutes or less. Regularly putting teflon powder on knuckles helps too, and some minor regulation every now and then is normal. That's how we earn our money. With all respect for a different way of thinking, I nevertheless always aim for a 'reasonable' perfection. That makes money too. friendly greetings from André Oorebeek Antoni van Leeuwenhoekweg 15 1401 VW, Bussum the Netherlands tel : +31 35 6975840 gsm : +31 652 388008 www.concertpianoservice.nl "where Music is, no harm can be" -------------- next part -------------- An HTML attachment was scrubbed...
