GAMMA CORRECTION for Two Instruments（2021）

Groupe des quatre et ses ami(e)s is an ensemble that shares with composers and audiences the excitement generated at the moment when a new piece is born and it has served as a stimulus to me since my student days. I feel enormously privileged to be able to participate as a composer on this occasion.
The title Gamma Correction refers to the manner in which the brightness of images is corrected when they appear on a screen. The idea for the piece came from the way that the degree of brightness changes little by little as it is being corrected，and I attempted to realise this idea through the interplay between two instruments. The mandolin and the guitar are both stringed instruments with a delicate tone but whose attraction lies in the manner in which they generate a sound that hints at the very origins of sound production. But the two instruments differ in that whereas the mandolin employs courses of doubled strings tuned in unison，the guitar uses single strings. Following the passage of sound while observing these tonal differences between the two instruments，I found that the way I was focusing on sound was changing and had progressed far from the point of departure. It was in this frame of mind that I began working on the piece，which allows for performance by combinations of instruments other than just mandolin and guitar. (distributed at the pemiere)
