The sounds available to you when you play are not limited to what you do with your hands. It works like the diaphragm in a loudspeaker, and is driven by vibration from the strings. It is best to have a used piano checked by a qualified piano technician to fully evaluate the piano soundboard and its condition. The soundboard is the major sound radiating component in the piano. If the crown is lost, soundboard replacement may be necessary to obtain good power and tone. Weight would vary from 150 to 250 pounds depending on the pinblock, tuning pin and string. A full-parameter frame should be around the same degree as this, but a thicker frame with a higher level of compression is possible. Soundboards that have several cracks, mostly due to age and/or large fluctuations in humidity over the life of the board, can lose crowns which would result in dull lifeless tone quality. How Heavy Is A Piano Soundboard The weight of upright piano strings is normally between 150 to 200 pounds. The Crystal Soundboard is the name of the glass soundboard for pianos and grand pianos, invented and developed by piano engineer C.J. It can be repaired with re-gluing or even shimming.

However, it can cause buzzing from certain frequencies. This is not detrimental or life ending for the piano. Older piano soundboards often form cracks, especially where the thin boards are glued together. The bridges are usually made from maple and their primary function is to transfer the string vibration to the soundboard. The best results are obtained when the grain of the soundboard runs parallel to the bridges. Wood for soundboards, usually spruce, needs to be light and elastic. The back of the soundboard has ribs made of wood that are glued to the soundboard to strengthen and support the crown. The soundboard has a crown which is very important to the tone and resonance of the piano.

PIANO SOUNDBOARD FULL
If the mechanical parts inside a piano are new, same logic applies for pianos too, at least in my opinion.Piano sound boards are thin boards commonly made of spruce approximately 3/8″ thick glued together and extend from the bottom of the piano on a vertical, and the tail of the piano on a grand, to the pin-block and then across the full width of the piano. Each one of our soundboards is carefully hand-cut, sculpted, and sanded to reveal its musical potential. Our soundboard master-craftsmen adhere to those original hand-crafted standards. Department of Physics, 1396 Physics Building, Purdue University, West Lafayette, Indiana 47907-1396. For nearly 120 years Steinway crafted their soundboards by hand. Mechanical impedance of a piano soundboard. See violins and guitars - they sound better and better with age, vintage wood instruments are much more expensive than new ones. Soundboard craftsman to authorized Steinway piano dealers. Because wood vibrates more freely with time - the resin is crumbled. Personally I often prefer the sound of old brand pianos, if they are optimal restaured, over the sound of new ones. All who heard the piano gave kind comments on the sound, so it worked. After that they filled the cracks, and put the soundboard back to convex shape. During restauration, they dried the piano down to 20 percent humidity, so that even some more cracks occured during that. If there is something wrong here, that has a much more influence on the sound. Because the distance strings to soundboard and the tension inside the soundboard is of importance. Much more important is for a grand, that the soundboard does not start to hang down instead having a convex dome. So even if there are 10, 20 cracks, it will not change the sound, or only almost unaudible. See for a better understanding the informations from the steinway website:Ĭracks are not that problem because they are in the direction of the strings and not in crossed direction. I disagree that if there are cracks in the soundboard that it would be better to leave it for museum.
