Faces (Face 12, Face 18) 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 these pieces.
