Faces(Face 14, Face 15, Face 16) for string quartet is one of the compositions from my musical oeuvre called “musique relative”.The concept of “musique relative”implies that melody and harmony, deformed by glissandos and quarter-tones cannot be interpreted in any other way than “relative melody and harmony”. Glissandos are the main characteristic of this piece. Namely, melody and harmony are permanently deformed by glissandos, from the very beginning all the way to the end of the composition.
