Why does a piano need maintenance? Regular maintenance is essential if a piano is to continue to play and sound at its best. The mechanism has over 1000 moving parts, which are subject to wear and tear and therefore need to be regulated to ensure optimum performance and feel. Unevenness of tone can be remedied by skilful voicing of the hammers to give a good overall balance.
调音是复杂且富有人文艺术性的工艺活动，如果选择机器的话则没有任何情感。所以，即使机器调出来的声音完全是标准化的可操作，但是比较死板或者说没有人味的魅力，当然也包括没有任何色彩可言。而人耳调音及整音完成后弹奏出来的声音，是有曲线和有色彩的。真正的调音是决不可以用机器的来取代的，借助软件和机器达到高标准精调音乐会标准是完全必要的。在这点认识上美国的本土调音师是非常胜任且采纳软件辅助调音的。（Voicing 整音服务 7188857986）
Tuning is a complex and artistic craft activity. If you choose a machine, there will be no emotion. Therefore, even if the sound tuned by the machine is completely standardized and operable, it is relatively rigid or has no human charm, and of course, it also has no color. The sound played after the human ear is tuned and calibrated is curved and colorful. Real tuning can never be replaced by machines. It is absolutely necessary to use software and machines to achieve high standards of fine tuning concerts. In this regard, local tuners in the United States are very competent and use software to assist in tuning. (Voicing Sound Adjustment Service 7188857986)
