Gravity II, is the second piece that I explore the idea of the sonic realization of such natural phenomenon. Gravity has at the same time stability but also power that holds everything it surrounds it. The electronic sounds follow this quality and in a way the piano and the marimba move around that. The composition is based on the overtone and undertone harmonic series of G and on a specific intervallic relationship that is realized with rhythmical patterns in the middle section. The piece is written in response to the 350 years from the discovery of gravity by Isaac Newton (1666).
