2a.2 Wayne Stuart’s response to the string vibration test.

All comparisons need to focus on the specific differences the vibration modes have on the attack, decay and sustain transients.

Measuring the vertical and horizontal deflections of the stretched music wire is the purpose of this study not to incite subjective interpretation which is why the brand names must be removed.

In the case of the increased horizontal deflection of the wire of the traditional two pin off set, a decay/dynamic/amplitude graph should be displayed to indicate the decay trajectory specifically the influence of damping as the vibration mode changes from one plane to another.
(This graph should show a maximum dynamic range followed by a sharp drop in the dynamic spectrum followed by a gradual but increasing decay rate with variable frequency responses during that period. The nature of this decay transient should confirm variable frequency or internal tuning characteristics and dynamic responses producing periodic damping that reduces the overall sustain envelope). (Damping equals energy loss.)

In the vertical agraffe example the vertical deflection needs to be displayed in a decay/dynamic/amplitude graph displaying the impact of the long period of time before the string makes its initial horizontal excursion and the influence this has on the dynamic range in the initial period of the
