鋼琴調音師 話你知 – 甚麼是 Regulation?

本集講解 甚麼是 Regulation
Piano Technician Guild (PTG USA) 的 Definition:
What is regulation?
Regulation is the adjustment of the mechanical aspects of the pianos to compensate for the effects of wear, the compacting and settling of cloth, felt, and buckskin, as well as dimensional changes in wood and wool parts due to changes in humidity.
If I have my piano tuned regularly, why do I need to have it regulated?
While tuning corrects the pitch of your piano, it is only one component of a complete maintenance program. Regulation attends to the touch and uniform responsiveness of your action, all vital to making each performance pleasurable. In addition, regulation ensures that your instrument is capable of producing a wide dynamic range — a critical factor, particularly in pianissimo passages
為什麼在香港許多人 (包括許多鋼琴老師) 都未聽聞 Regulation的重要性?
做完 Regulation 後, 鋼琴會有甚麼分別?
鋼琴是一項結構精密的樂器,內部包含數千個相互連動的零件。隨著時間推移,木材、氈料與皮革等材質會逐漸磨損或壓縮,導致觸鍵手感與音色表現出現不均。所謂「鋼琴整調」(regulation),即是透過專業技師對鋼琴擊弦機構進行精細調整,使其回復至理想的演奏狀態。此過程對於鋼琴的可演奏性與音樂表現力具有關鍵影響。
什麼是 Regulation
鋼琴整調指的是對鋼琴「動作機構」(action mechanism)進行全面性調整,以確保每一個琴鍵、琴槌與制音器能夠協調運作。其主要範疇包括:
-
鍵盤高度與下沉深度:確保每個琴鍵高度一致,且下沉距離適中。
-
Hammer alignment & travel:調整琴槌擊弦角度與路徑,使其均勻敲擊弦線。
-
Let-off:設定琴槌在擊弦前適時脫離,以確保靈敏度。
-
Repetition springs(三角琴):調整彈簧,使快速重複彈奏更為精準。
-
制音器:確保制音器能均勻抬起與落下,正確控制延音。
-
觸鍵重量與平衡:使整體鍵盤的阻力一致,手感自然。
整調頻率建議
-
家庭使用(輕度彈奏):約每5至10年一次 (取決於鋼琴狀況, 需鋼琴技師的專業檢驗)
-
專業或高頻率使用:建議每年一次
-
新琴:購買後一年內通常需進行一次整調,以因應零件沉降
-
大修或更換零件後:必須重新整調
