11. The piano was an upright made by the Charles Fredrich Stein Company in approximately 1935.
12. The free-standing soundboard was taken from an Estey spinet piano.
13. Two different accelerometers, both obtained from PCB Piezotronics, were used. One (model 352B68) had a mass of 2.0 g, while the other (model 352A10) had a mass of 0.7 g.

15. The microphone was a model 130A10 from The Modal Shop, Inc.
16. The shaker was a model V102 from Ling Dynamical Systems.
17. b. In order to facilitate comparisons we used approximately the same frequency resolution in Figs. 1-3 and 7. This resolution varied smoothly from ∼12 Hz at the lowest frequencies, to ∼50 Hz near 1 kHz, to ∼300 Hz at the highest frequencies. The frequency resolution was much wider for the measurements in Fig. 8 (as evidenced by the spacing between the data points), and was near 100 Hz at the lowest frequencies, and 300 Hz near 1 kHz. For this reason, the fluctuations appear smaller in Fig. 8.
18. b was under-estimated in Refs. 3 and 4, due to a mechanical decoupling of the accelerometer from the soundboard.
19. b, impedance measurements are not required for the analysis.
