This consists of two pieces, played in an order the performer chooses. The number five, closely related to the nature of the zortziko, a Basque dance in 5/8, has been applied to several musical parameters such as repetition ofpitches, superposition of five separate layers, fragments of pentatonic scales and the metrical structure. The piece explores extensively the percussive and resonant nature of the piano.
