42a. Vibration beat--D(148Hz)--on floor--
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.

41d. Vibration beat--A(221Hz)--COMPARISON--Lower bout--
Comment:
The vibration of the lower bouts of cello weaken by setup of the endpin and accelerated by placing on the floor.
Yellow areas come out around 2.0 second at 'without endpin', meanwhile around 1.5 second at 'with endpin'.

41c. Vibration beat--A(221Hz)--without endpin--
Comment:
Top plate and the lower bouts seem to be interacted each other and acting naturally as an united instrument.

41a. Vibration beat--A(221Hz)--on floor--
Comment:
Top plate vibrates for long time and the second longest part is the endpin.
The lower bouts seem to shorten their vibration time and might be acting as a fulcrum(てこの支点) when a cello is placed on the floor.
