Éxtasis is a Spanish word describes the state of « ecstasy » or « rapture ».  As the title suggests, the music is spontaneous and highly elaborated, and meant to be a « show piece » for the violinist’s virtuosity and musicality. The thematic materials of this composition are built on fast rhythmic figures that emphasize the interval of fifths, also constantly outline the tonal areas which based on the open strings of the violin. The slower enigmatic middle section depicts the « altered ego » or « trance » of Éxtasis; it is an imaginary conversation between two voices created by alternating reflective passages of string’s harmonics with miniature runs on high register. The music continues in high energy, which brings the rhapsodic and capricious nature of the composition to a climatic conclusion.
