This work seeks to explore the relationship between two arts: music and painting. The aim of this thesis is the creation and execution of an interdisciplinary performance in which music and painting dialogue live, "Painting music", to investigate how both arts relate and influence each other when they are part of a single artistic act and how performers and audience perceive this relationship. To do so, we will investigate interdisciplinary performances, synesthesia (union of perceptions) and the different ways in which painting and music can relate to each other.
