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。)

4C7G. Cello-1 G(98Hz) on C-string Simulation x80 slower

[ 4/18/2020 ]     Labels: 4C7G.Resonance C

 
G note on C-string(98Hz, 4C7G, bowing) Typical Resonance Simulation:
Cello body takes a single beat resonance in spite of various endpin environments.
G(98Hz) note seems to be the lowest frequency that cello body can resonate by a single swing.
(C線のG音、チェロが胴体全体を使って１ビートで共振できる最低音のようです。)

4C4E. Cello-1 Simulation x70 slower

[ 4/10/2020 ]     Labels: 4C4E.Resonance C

 
E note on C-string(83Hz, 4C4E, bowing) Typical Resonance Simulation:
On cello's low notes(C - F#), down beats from C-string need to be added cello body's up beats and completed by. However the extended height of body by deployed an endpin misses ideal up beats and weaken the resonance amplitude. 

(C線上のE、エンドピン装着によりチェロは裏拍をうまく刻めず結果として十分な共鳴を実現できていません)
