Mirroring is a study for four percussionists, on the phenomenon of sound reflection. Commissioned by the percussion ensemble Drumming, this study is dedicated to Miquel Bernat. The work is entirely composed for boomwhackers: tempered percussion instruments made up of tubes of different sizes and colors. This playful piece develops different types of echo throughout its duration, composed by the interaction of the different musicians. The world premiere of Mirroring took place on July 1, 2023 by the Drumming Ensemble at Casa de Mateus, Vila Real, Portugal
