    中秋佳节倍思琴—贝希斯坦(A175)的音色 Mid-Autumn Melancholy: Longing for the Piano—The Exquisite Tone of C. Bechstein (A175)

    月光所照皆为故乡, 双脚所踏无非过往; 愿你历尽阴晴圆缺, 依旧星月交辉岁月。 Wherever the moonlight shines, there lies our home; Wherever our feet tread, it is but the past. May you journey through all of life’s waxing and waning, Yet still find your years illuminated by the eternal glow of stars and moon. 一晃一年的中秋到了,去年的中秋弹奏的视频今年再看看……多年调音体会之一:贝希斯坦钢琴均在德国工厂调音至标准音高 A4 = 445Hz,钢琴预计在这种情况下从工厂发货运输到客户的家中,高张力补偿了新琴弦在第一年内的大量变化。(调音新标准须依据客户要求或音乐会演出标准而确定音高440-442Hz)In the blink of an eye, another…

    数字化实证:大幅度提升音高(Pitch Raise)中超调曲线的力学逻辑》—纽约钢琴技师 https://www.interpts.com/index.php?c=show&id=5452 Abstract This research note investigates the mechanics and materials science behind substantial piano pitch raises. By analyzing four key physical dimensions—pinblock friction, soundboard flexural rigidity, music wire stress relaxation, and environmental thermal compensation—this paper demystifies empirical tuning craftsmanship based on electronic tuning device (ETD) telemetry data. It provides a technical analysis of…

  • 佩卓夫(PETROF)钢琴的平均律与“狼音”之间隔(2025)

    佩卓夫(PETROF)钢琴的平均律与“狼音”之间隔In a Petrof piano, this refers to the interval between equal temperament and the “wolf tone.”检查一架十多年没有调律的佩卓夫PETROF三角钢琴骤然发现了狼音音程Wolf Interval,无法确认当年的调律师是如何为了保证五度纯净,把这误差24 音分全部“塞进”最后一个五度导致其产生狼音的。狼音的产生也是因为数学上12个纯五度不等于 7个纯八度,两者之间存在约 23.46 音分的余数(称为毕达哥拉斯增差)。  很久没有谈及十二平均律的比例与五度音程,如何达到物理上的“完美纯净”。特别是让所有半音之间的比例完全相等(约1.05946),其奥秘在于将这 24 音分的误差被平均分成了 12 份,每个五度音程只分担约 2 音分的极小偏差,从而实现了自由转调。十二平均律通过均匀分配误差,彻底消除了狼音音程Wolf Interval。 感恩早年母亲的教诲让我学习了音乐且多次弹奏舒曼的《梦幻曲》记忆犹新,然早年狼音的存在大多与乐器的构造及局限性有关,特别是大提琴等弦乐器。多年后的理论与实践,特别是琴体共振频率与琴弦频率冲突等物理杂音与律法等受益匪浅。此次调整非常成功且主人欣赏之余额外小费$88红包!祝各位节日快乐!2025-12-16于纽约 In a Petrof piano, this refers to the interval between equal temperament and the “wolf tone.”Inspecting a Petrof grand piano that hadn’t been tuned for…

    九月美国纽约的秋热余温尚未褪去、然一派忙碌的日子已书归正传。按照预约来到一个犹太人之家,嫣然一笑的大女孩弹奏着贝多芬的爱丽丝,不协和的琴声来自于一架小三角钢琴,KNABE (185102)1975 年左右生产的。序列号在 197840 以内且为纯数字,说明这是一台纯正的美国产老琴。(If the serial number is 197,840 or lower and consists solely of digits, it indicates that this is an authentic vintage instrument made in the USA.)
