A(221Hz)-G(393Hz) notes on A-string were studied. Conditions and methods are very similar to the former C(66Hz)- research, however an old German cello additionally participated in this measurement mainly testing several tailpieces/tailpiece weight.
The frequencies of notes on an A-string are just overlapping with that of endpins/rods/pipes adjusted around 300mm length(between fixed two points). Something new topics on resonance might come out.
C線上のC-G音の観察に引き続き、A線上のA-G音について詳しく調べてみる。
調査方法と条件はほぼ同じであるが、チェロを2台使い、テールピースの影響(関与)についてもチェックする。
今回調査対象のA線上の音域は、エンドピン(棒・パイプ)が300mm前後の長さで2点を固定された時に大きく共鳴する周波数と重なっているため、エンドピン・床の影響をはっきり見ることができるかもしれない。ちなみに Cello-(2)はA線がよく響くように調整してある。
Cello-(1) : Filip Kuijken 2011 (8-year-old) with carbon/steel-pipe/Ti endpin
Cello-(2) : Made in Germany (estimate 114-year-old) with steel-pipe endpin changing tailpiece/endpin length
Mezzo-forte, down bowing
