To Keys60 and Dan Silverwood,
As a concert technician with 34 years experience, I would suggest to the forum that both these people have made correct and proper points.
Tone and volume are separate things.............
Furthermore, voicing a piano properly is much more than sticking needles into hammers OR conversely applying 'hardener'.
Yamaha actually uses a 'hot' press to make the hammers thereby creating a 'harder' hammer to cater to modern piano 'tastes'. Actually, many of 'us' in the industry recognize it is easier to develop 'tone' for the layperson with a minimum of work starting with a harder hammer. The down side is that it quickly becomes an ongoing voicing issue throughout the life of the 'well played' piano. (Much like painting brick...........once you paint, you are forever obligated to repaint)
I was trained both in US and in Europe and old-style German voicing is more concerned with working quite deeply inside the hammer to balance out compression and YES, it CAN last a goodly long while if done properly. Furthermore, touchup voicing is restores the tone back to the original sound if hammers are not too flat.
Voicing in this way is not the pervue of the average technician as most tend to concentrate on surface crown voicing in general. Remember, ALL voicing is founded upon the proper preparation of hammers, fitting to strings (hitting all 3 at same time), leveling strings therefore and reasonable action regulation.
Those technicians on this site who speak freely and offer their advice should be valued by the musicians as generally you might find yourself paying for such knowledge.
Furthermore, there is NO room for rudeness of any sort on the internet.
That, my friends, might be a contributing factor to war and hatred amongst people.
Music is about sharing human decency, sensitivity and expression!
Just my thoughts on the matter.
