GeoMusica is a tool to make music with geometry. Compose geometries and listen to the musical translation in realtime, perform and experiment with the Sacred Geometry inspired methods and be amazed by the beauty hidden within the Mathemagics.

It is structured as a multi-layer composing tool, focused on geometrical parameters that can be set with special proportions and shapes, and should be used has a MIDI note generator, connected with your favorite electronic instruments to reproduce the musical output. Therefore, should be considered as a generative MIDI sequencer in terms of families of musical software, and its aimed at musicians that use electronic tools for creation.

This project started as a personal research on Sacred Geometry studies, within the scope of the 3 year introdutory course that I attended led by Prof. Luis Elye, to the amazing field of knowledge hidden inside the Traditional geometrical legacy. with roots lost in time, this knowledge proved fundamental in bringing ordered geometrical shapes that generate meaningful musical correspondance, and revealing a hidden structural connection between geometry and music that becames obvious when exploring this tool.

As the research evolved, I’ve managed to do some outputs in form of talks and live concerts, that generated a surprising reaction on the interested audience, namely my fellow colleagues geometers, the TD artists community, and the Boom Festival community. that feedback gave meaning to the publication and release of this tool.

The aim for publication is to support the further development of this tool, either by other developers in the open-source spirit, or by anyone that use this tool and want to help supporting via the Patreon platform.

It is also a way of retribution to the fantastic TouchDesigner community, that along the years of using TD allways gave generously without asking for return.


GeoMusica é uma ferramenta que permite fazer música a partir de geometria. Permite compor formas geométricas e ouvir a tradução musical em tempo real, usando métodos inspirados em Geometria Sagrada. Tenta revelar a beleza escondida dentro das matemágicas. 

Está estruturada como uma ferramenta de composição multi-camadas, focada em parâmetros que podem ser definidos com proporções e formas especiais, e é usada como um gerador de notas musicais MIDI, ligada a instrumentos musicais electrónicos para reproduzir o resultado musical. Assim sendo, deve ser considerada como um sequenciador MIDI generativo em termos das famílias de software musical, e está destinada a ser usada por músicos que usem ferramentas electrónicas para criação.

Este projecto começou como pesquisa pessoal nos estudos de Geometria Sagrada, dentro do âmbito de um curso de 3 anos de introdução ao campo de conhecimento pertencente ao legado dos métodos tradicionais, dado pelo prof. Luis Elye. Com as suas raízes perdidas no tempo, este conhecimento provou-se fundamental para revelar formas geométricas ordenadas que produzem correspondência musical significante, e para revelar também uma ligação estrutural oculta entre a geometria e a música que se torna óbvia quando se explora esta ferramenta.

this public release of geoMusica is dedicated to my grandfather Francisco Alves Gato. I did’nt had the luck of meeting him personally, but I know that he, has many of us before and certainly after, was one of the humans that felt the sparkle of the search for Knowledge and Beauty, which led him to research on a special tuning for the Portuguese Guitar. I know we would had good times together playing with geoMusica!
