43e. Vibration beat--G(98Hz)--COMPARISON--Top plate--

Comment:
(1) Cello's top plate and also the endpin continues the clear vibration over 3 seconds after a pizzicato of G note(open string).
(2) The vibration of the lower bouts gradually fades out around after 1.6 - 2.5 second when the endpin is set up and placed on the floor.
The lower bouts and tailpin might to be acting a role as a fulcrum of seesaw. If this is true, there is a possibility that the center resonance area of modern cello('endpin-cello') might slightly be shifted to the upper hemisphere as compared with the design of Stradivali, Montagnana etc.
(3) Cello's top plate generally fluctuated with the beats 3->2->3(->4)->3->2->3 .
On the other hand the endpin kept 3-beat homogeneously.
42e. Vibration beat--D(148Hz)--COMPARISON--Top plate--
Comment:
Cello's top plate vibrates(/fluctuates) with beats 2->1->2->1->1 after a pizzicato, on the other hand the endpin keeps 2-beat persistently.
However both two components of cello sustained their vibration over 3 seconds in this measurement. The D note(148Hz) might be well matched to the top plate and also to the endpin on the floor or to their combination.
