ABSTRACT (English) Synesthetic Tone: Relations between the tone of the music and color through a personal proposal. The concept of "Tone" is a concept that ranks the tones and colors in the disciplines of music and visual art to the present day. This feature helps to establish the functionality of the elements in a musical piece or a two-dimensional or three-dimensional space, determined by the colors in use. With the concept of a "Synesthetic Tone" we will refer to a relationship of correspondence between tuned sounds and colors, as determined by the vision of people suffering clinical condition called "synaesthesia." From the establishment of the elements that form the concept of tone in each artistic discipline individually, we’ll join the elements of tonality in music and painting, from a review of the perceptual phenomenon of synaesthesia. The objective of this thesis is the creation of a new concept known as "Synesthetic Tone" which constitute a new correspondence between artistic disciplines, in addition to extracting interdisciplinary ways of working that have transcended in the history of art, and with them, formulate a new way of working in the field of translations of music to color, and musical composition. This research is based mainly in the inductive method, on the observation of different ways of working in the field of interdisciplinary art, and personal creative work patterns, extracted from studies of synaesthesia (RE Cytowic, John Harrison, Paul Hertz and Flournoy, among others) and the theory of music and color (John Gage, E. Goldstein, Scriabine, A. Schoenberg, Kandinsky, Messiaen, Ligeti...), in order to create the basis of a code of relationships for the establishment of a concept: The "Synesthetic Tone". The results achieved in this research are to be found particularly in practical experiments, first taking the form of translations of historical music composers (JS Bach, Claude Debussy and Arnold Schoenberg) and taken to painting, and second, by composing new music (a piano miniature and a "Trio for marimba and two vibraphones") whose elements were built using criteria of color harmony in different formats of instrumentation and duration, and its public premiere in a multimedia concert ("International Festival Cervantino 2010"), so the creative possibilities of the “Synesthetic Correspondence” were demonstrated.
