Hmm, I may have been misunderstood. I was speaking of how I approach
Steinway hammers that have become harsh.
I prefer the Renner hammers, and am considering using the Ronsen
Wurzens on the next Steinway. However, I do have to work with Steinway hammers
when I have a new piano to deal with. In the school setting, the problem begins
after the first year, when the hammers begin to become harsh. I do have
customers that want Steinway parts, so I give them Steinway parts.
Now, to consider several things: the Steinway hammers don't take more
work, voicing with lacquer is much easier than the exhaustive accupuncture that
Renner Blues require. I also think that the Steinway hammers can provide better
tone than anything else, for just a little while, but they are NOT durable.
It is a lot like the tires that Nascar racing cars use,which provide better
traction than anything you can get in the store, but you have to change them
every 20 miles. The soft wool/ excessively lacquered hammers (Swells) provide
a great tone, but after they have been played a year or two in the school
environment, it becomes difficult to maintain the range of mellow
pianissimo/brilliant forte. Needling these sugar cubes kills the offending ping, but the range
begins to disappear.
If there is a school that can afford to replace hammers every two years,
the factory hammers are the way to go. However, longevity is a prime
consideration for CAUT work,(at least, it is here in Gnashville), and I have too much
other wear to address in the school to bleed the maintenance budget keeping the
stage pianos sublime with factory hammers. Renners do fine over the long
haul. They take a lot more work, up front, but they can go 6 years or so before
becoming narrow in their range.
I preferred the un-treated factory hammers, because I could lacquer them
as per the older method, ie. I soaked hardener into the shoulders until the
solution reached the tip of the core from both sides. This usually allowed me
to put them into service as "mellow" and with some playing to compact the
surface, the hammers began to "speak" after perhaps 40 hours of play. Sometimes,
I had to add an eyedropper full on the sides, right at the tip of the core,
so that the soak area moved closer to the strike point. Hammers thus treated
would hold their tonal range for far longer than what I find now. Sometimes I
have been able to introduce solvent at the crown to remove some of the
harshness.
What I find from the current factory offering is a hard hammer that
sounds loud, but lacks body at a distance, (like the middle of a 700 seat hall).
This became evident last year when a new D was played next to a much older D
with 5 year old Renner blues on it. On the stage, the new piano seemed much
stronger, the old one seemed mellow and lacked "power". HOwever, out in the
hall, the new piano sounded stringy and thin while the older piano sounded full
and resonant. Experienced performers that pay attention understand this, but
many pianists simply go by what they hear on the stage, <sigh>
Power comes from the lower frequencies, a hammer must be resilent to
produce them. Definition and clarity come from the higher frequencies, the hammer
must have some stiffness to create them. Getting a hammer to possess all of
these qualities requires a rock hard deep inner core with a certain amount of
resilience above it. This can be done with lacquer, if it is kept away from the
outer surface at the strike point. But this capacity seems to be more
rapidly perishable on the heavily lacquered hammers, that is why I prefer to take a
highly compressed hammer and introduce the non-linear flexibility with
needles. I can keep the tonal range in play for a far longer time.
Just my too-sense worth,
