Twelve freely composed preludes, all of which require some degree of virtuosity from the performer. Two of the pieces are arrangements- number one is an arrangement of the first of my February pieces for piano solo; while the ninth prelude is an arrangement of the traditional Japanese folksong Songs at Mamuro River. The other pieces explore a range of melodic and harmonic figures, especially those based on the intervals of a third and fourth, and range from written out improvisations to dance-like numbers. I would like to thank Kazuhito for his advice while composing these preludes. Commissioned by and dedicated to Kazuhito Yamashita, and first performed by him along with solo and ensemble pieces by Chinary Ung and Josefino Chino Toledo in Kyoto and Tokyo in November 1997.
