鋼琴多久調音一次？各大廠商官方建議
國際鋼琴技師協會（PTG）收錄的專業指南
為什麼需要定期調音？
鋼琴是一種非常「敏感」的樂器——極精緻卻又極脆弱，因此為了使它保持良好狀況，一直符合彈奏者的要求，所以鋼琴調音是絕對必要的。
鋼琴的琴弦共約210~230條，而每一條弦的拉力約90公斤，即使不經常使用，琴弦也會鬆弛，使音律不準，因此定期調音是必要的。同時將鋼琴的整個狀況仔細檢查，尤其是調整觸鍵及音色，在平台型鋼琴就顯得特別重要。
因經常使用而消耗與疲勞的部品，可即時更換或整修；使其處於最佳的彈奏狀況。故請務必半年調律乙次。

國際大廠官方建議

新琴第一年建議調音四次，之後每年至少兩次。
In the first year, the National Piano Manufacturers Association recommends that you have your piano tuned four times... After the first year, the piano should be tuned at least twice each year.
Kawai Piano Company
新琴第一年至少調音四次，之後每年至少兩次。同時應定期進行整調與整音。
A new piano should receive at least four tunings in the first year. After that, the type of use and the location of the piano will dictate the number of tunings required, but Kawai recommends two tunings per year as a minimum.
Pearl River

總結與提醒
綜合各大廠商建議：
- 新琴第一年：多數品牌建議調音 2~4 次，以穩定琴弦張力。
- 日常保養：一般家庭每年至少 1~2 次；經常演奏或環境變化大者應增加頻率。
- 專業用途：音樂廳、錄音室等需更頻繁調音（甚至每場演出前）。
- 定期調音時，也應請技師檢查整調與整音，讓鋼琴始終保持最佳狀態。
