Ron, What can you tell us about this particular video?? Who did it, what the materials used were, etc. It might be very interesting to look at the relationship(s) between the frequencies involved at the moment(s) of change of pattern. Perhaps if we had enough data, from enough different and carefully measured and monitored soundboards, it would really be possible to begin to predict what will happen with given parameters of stiffness, thickness, etc. Ya think??
