MARS is a solo piano concert created by the Brazilian composer Emanuel Dimas de Melo Pimenta. The piece was made in memory of the great teacher and musicologist Maria de Lourdes Sekeff and dedicated to her son, the musician Edson Zampronha - both friends of the composer. MARS is entirely composed after images of the surface of the planet Mars. It is structured on sixty short movements, like musical hai-kais. Those movements can be freely determined and assembled by the performer. The complete piece lasts sixty minutes. It is a musical piece full of silence, where it no longer is restricted to an element of expression; it is music, in its deepest sense ? reminding much of John Cage's music. The durations of sounds and of silent moments obey to different logical structures.
