Jishin (earthquake) is a musical composition written for full orchestra, based on a twelve-tone row. The twelve-tone row is structured such that it contains only two musical intervals (perfect 5 th , major 3 rd ). Due to the nature of the row, various transpositions of the row can be used to form what seems to be a never ending cycle of pitches. Throughout the composition the material of the row is fragmented and used motivically to develop larger structures within the whole of the piece. Like an earthquake, Jishin strives to create an enormous amount of tension and aggressive energy. At the end, the moment of strongest tension, the original row is set against itself in retrograde, metaphorically representing the friction caused by plate tectonics.
