Abstract: This paper studies the relationship between synaesthesia as a neurological condition and synaesthesic metaphor.
It aims at investigating synaesthesia as a way of conscious listening and proposes a synaesthesic listening of the
5th movement Joie du sang des étoiles of Olivier Messiaen’s Turangalîla, including an analysis of the relationship between
the elements found in the synaesthesic listening and the structure of the work. Relating analysis and phenomenology, it
also suggests a systematization of synaesthesics categories, departing from the sound as the primary sensation among the
most common sensations.
Keywords: synaesthesia, listening, music analysis, composition, Messiaen.
