The Importance of a Soundboard

When you take a peek underneath the lid of a grand piano you may notice a shiny piece of thin wood beneath the cast-iron plate. This is called the soundboard. Four or sometimes five pieces of wood are cut to precise dimensions and glued together to form the soundboard. On top of the soundboard are the cast-iron plate and the pin block. The soundboard amplifies the vibrations of the strings. Think of it as a guitar amplifier that doesn’t need electricity. The vibrations travel through the bridges and down to the soundboard. Without a soundboard, the piano would be hard to hear.

Fixing Cracks in the Soundboard

Whether it’s a grand or an upright, cracks in the soundboard are the most common repair pertaining to this particular part of the piano. Mainly climate changes over the years can cause cracks, and even just wear and tear from the years of vibrations. Some cracks don’t create a noticeable difference in sound, hairline cracks in the wood are quite common and not usually serious. In the case of an environmental shock, like a flood or a sudden drop, you may notice a much deeper crack in the soundboard. This can be a cause for concern especially if you notice a rattle or a buzz when you play the instrument.
