A one$-$string Aeolian harp is constructed by attaching the lower end of a $1\mathrm{.}56-$m$-$long rigid and uniform pole with a mass of $9\mathrm{.}00$ kg to a tree at a pivot and then using a light rope to hang a $39\mathrm{.}0-cm-$long hollow steel tube with a mass of $4\mathrm{.}00$ kg from its upper end. A horizontal wire between the pole and the tree is attached to the pole at a height $h$ above the pivot and holds the pole at a ${45\mathrm{.}0}^9$ angle with the vertical. The wire is uniform and has linear mass density $=1\mathrm{.}40\frac{g}{m}.$ When the wind blows, the wire resonates at its fundamental frequency. The height $h$ is chosen such that the sound emitted by the wire stimulates the fundamental standing wave in the tube, which harmonizes with the resonating wire. The speed of sound in air is $344\frac{m}{s}.$
