...Correct Responsive Touch and Feel...
A
piano’s working mechanism (the action) represents the engine of the
instrument. Those who play the piano expect the working mechanism to be
responsive. Here we will take a closer look at both the vertical and grand
working mechanisms.
Vertical
Piano Actions
Each
Rawlins & Co. vertical piano uses a working mechanism produced by a fourth
generation action maker. Every part of the construction of a piano
requires much hand-work by skilled craftsmen.
Producing and
assembling the thousands of parts that make up just one piano action
proves no exception.
Maple used in the
action comes from forests in Germany.
Material will be
kiln dried before it goes into work.
Hundreds of steps
later, the action will be completed.
This working mechanism, used exclusively in Rawlins & Co. vertical pianos,
will also be found in the inventories of select German action makers.
Lead
weights inserted in each key ensure perfect balance and touch for the
performer. Most teachers insist their students’ practice on an instrument
with the accepted fifty six gram touch. Rawlins & Co. weighted keys help
achieve this crucial speci
fication.
Vertical keys
utilize cross laminations of spruce to assure stability. A maple button
has been affixed to the top of the key at the balance rail and at the back
of the key where the capstan will be affixed.
Each of the three pedals employ solid brass construction The most used
sustain pedal rest on the right. A soft (pianissimo) pedal sits on the
left. When a player tackles repetitive scale exercises the middle pedal
may be used. A piece of felt comes down between the hammers and strings
which dampen the sound without appreciably affecting the touch and feel of
the keys.
Grand Piano
Actions
Piano students
and performers may spend many ho
urs
each
week
at the keyboard of their grand piano. Several critical regulations help
the builder create an instrument that will be a joy to play.
Actions used in
Rawlins & Co. pianos come from a modern grand piano action facility in Hamamatsu,
Japan. Clear, white spruce keys will be a joy for performer and student.
Some Japanese action makers use plastic (ABS) parts. Quarter sawn maple
components have withstood the test of time in all of the world’s premier
pianos.
Rawlins & Co. grand actions use no plastic (ABS).
In the grand
action the hammer will be lifted to the string. Gravity brings it back to
be played again. The larger bass hammers weigh more than the treble
hammers. Lead weights placed in the keys assure that touch will be uniform
from key number one to key eighty eight.
When played, the
hammer will be thrown to the string. The hammer should let-off (when the
knuckle leaves the jack) about one-eighth inch from the string. Too little
let-off results in a blocking key. Too much let-off makes the piano play
hard and sluggish.
The repetition
feature helps the player breeze through the most challenging passages.
Before Rawlins & Co. pianos are shipped factory craftsmen attend to each
minute regulation.
After decades of
use regulation adjustments must be made. If the original working mechanism
has been constructed from quality components and assembled by skilled
craftsmen it will be a joy for any technician to regulate.
Each Rawlins &
Co. grand piano has three pedals. Like the vertical, the most used sustain
pedal sits on the right of the three. The left, called the una-chorda
pedal, shifts the entire action to the right. Instead of playing two
strings the hammer strikes only one; instead of three strings the hammer
strikes only two. Dynamics can be described as the most important part of
making music. With a fine grand the performer can achieve the complete
dynamic range. The remaining middle pedal will be known as the sostenuto.
When you have this feature you can play a chord and sustain those notes
with the left foot on the middle pedal. Now you can continue to articulate
additional notes, using the right hand sustain pedal.
