Written in 2017, Estudio Rítmico for unaccompanied clarinet is dedicated to clarinetist Javier Vinasco who premiered it the same year in Bogotá, Colombia. The work is a tour de force featuring numerous technical and endurance challenges for the performer. The composer also wrote a shorter version of this work. The music shares thematic material with Aguila’s Wind Quintet No. 3, Quinteto Sinfónico and Sonata Flautísima. Versions for solo saxophone and solo flute are also available. The self-published work is recorded on the CD Silence by Javier Vinasco.
