4C5F. Cello-1 F(88Hz) on C-string Simulation x80 slower

[ 4/30/2020 ]     Labels: 4C5F.Resonance C

 
F note on C-string(88Hz, 4C5F, bowing) Typical Resonance Simulation:
Cello body resonates taking a 2-beat for F(88 Hz). Endpin also resonates itself taking favorite beats according to each material/length with the cello body. As a result, the lower part of body seems to be repressed a little bit when placed on the floor.
(C線のF音、チェロ胴体は2ビートで共振しエンドピンは独自の共振ビートを取っている。その結果、胴体下部の振動が若干押さえられているように見える。)
