I haven't heard any of the attempts to explain how firm frontrail punchings might affect tone...I'm curious since there's (hopefully) no connection to the frontrail punching during escapement or when the hammer hits the string...is it some kind of psychoacoustic phenomonem? Please elaborate. ~~~~~~~~~~~~~~~~~~~ Eric Wolfley Head Piano Technician Cincinnati College-Conservatory of Music University of Cincinnati ~~~~~~~~~~~~~~~~~~~ -----Original Message----- From: Richard Brekne [mailto:Richard.Brekne@grieg.uib.no] Sent: Friday, January 14, 2005 2:00 PM To: College and University Technicians Subject: Re: [CAUT] Andres punching tested Erwinspiano@aol.com wrote: > Hi Fred > They are stiffer than anything I've ever encountered & mostly > because it is not a woven cloth but a pressed felt.

You get this really nice feeling of hitting a very solid bottom while also experiencing a very pleasant <<spring>> back upwards... nothing too dramatic mind you, but noticible and nice. Then there is the unmistakable change in piano tone... harder to find an explaination for, but some of the attempts made so far seem to have some sense to them. In anycase its there.
