(a) Eigenfrequency versus the relative height of the glass rod, black crosses (×) refer to experimental frequency, colored crosses (+) correspond to the principal mode (closest to mode 7), colored points correspond to other modes; (b) Minimal applied force to destabilize each pole with = 0.1 m.s⁻¹, this playability criteria is calculated by LSA, the colors refer to the color of mode in (a); (c) rise time for each relative height of glass rod with F_N = 1 N and = 0.1 m.s⁻¹, black squares are calculated from the time-domain simulation; colored dots and crosses correspond to rise time calculated by LSA of each pole in (a); (d), (e), (f) and (g) represent the speed versus time with F_N = 1 N and = 0.1 m.s⁻¹: for the finger (orange) and for the resonator (blue). The envelope is calculated with LSA, the color corresponds to poles in (a).
