VOICING Voicing adjusts the hammer felt flexibility in order to achieve identical intensity and tone strength throughout the instrument range. After some time, every instrument has the hammer felt densified, which makes the tone clearer but uneven, given by the intensity of playing each key, climate change, etc. We recommend having the instrument checked by a qualified technician at least once during the warranty period (5 years). Further voicing is up to you and the time of use of the instrument.
