Patience is the mother of quality. Sometimes, 300 years of patience are necessary. This is the age of some of our mountain spruce wood which is utilised for the manufacture of the soundboards. This wood is cultivated in high mountainous areas under most difficult conditions. Only a minimal percentage of the wood produced, exclusively resonance wood, can be considered for the manufacture of our soundboards. The very best quality is a vital factor as the soundboards are the heart of our instruments: their vibration properties and stability are of decisive importance for the beautiful tone of our upright and grand pianos.
