The Fantasy for flute and piano was finished on March 31, 2007, and is dedicated to María Victoria Gómez and Alicia Correas, who premiered it the same year. The language is predominantly tonal, but certain passages use arpeggios with several just and augmented fourths, a characteristic technique in other works by the author. The work begins with a brief introduction followed by a piano ostinato which acompanies a very slow tetrachord in the low register of the flute, which will be used later as a motivic resource by diminution to different degrees. An episode with iridescent harmonies leads to a piano interlude featuring the arpeggios mentioned earlier and then a third theme is presented in which a chord counterpoint is pucntuated by several augmented arpeggios on both instruments. A new series of arpeggios of fourths, interrupted by a brief bucolic interlude, takes us back to the third theme and finally to the initial ostinato, which this time fades into one last arpeggio interlude. Then a lyric passage leads to a brief recapitulation. Although for a moment it seems that the work will be ending with a luminous G major harmony, the discourse is dramatically interrupted by a dark atonal coda.
