Abstract
Cello spiccato is known to be very hard to acquire. In this paper, we first identify the forced vibration as an adequate physical model to describe spiccato. We take two typical examples of the forced vibration; swinging and dribbling basketball. Then, from analogies of these two motions, we extract forcing timing and shock absorbing way to give the force as two important physical conditions to realize the forced vibration. Then we discover the ways how to satisfy these two conditions through meta cognitive experiments as well as discussions between two authors, an amateur cello player and a professional. Finally we clarify relationship among technical components to realize spiccato to get better explanation based on the inference diagram.
