Thunderscape was written to convey the grandeur and awe of one of nature's greatest spectacles, the thunderstorm. The frantic pace of the piece provides a backdrop for the main element of the thunderstorm, the thunder sheet. Preferably, two thunder sheets should be utilized with one on each side of the ensemble to create a 3-D effect. The thunder sheets should be played using a shaking method, and the resonance of the metal should be allowed to die off naturally. Strikes may be alternated when using two sheets to give a more realistic effect. This work places great emphasis on rhythm. Notwithstanding, there are several melodic themes that develop throughout. The first occurs at measure 12 in the brass, the second at measure 30 in the woodwinds, and the last in measure 71. The piece also eludes a tonal center. This is partly due to the free-form nature of the work. Like many thunderstorms, there is seldom respite from the deluge of chaotic impacts. Intensity and tempo remain constant throughout.
