T. Greguol combines the rigidity of mathematics with creative freedom in an instrumental album


With the collaboration of 26 composers, a mathematician and a theorem, an artist from São Paulo creates a formula that pays homage to the creative processes and the discovery of new ideas

A mathematical theorem, responsible for imposing a rigid structure for musical composition, determines when and for how long each musician should play, without limiting the nature of his contribution.

This is how the São Paulo artist Térsio Greguol, known as T. Greguol, translated the instrumental album BOOMa tribute to the creative processes and ideas that form gradually and suddenly appear ready in your mind.

The Art of Mathematics

The relationship between art and mathematics as a source of proportion and harmony can be observed since ancient times. Years later, the works of the Italian Leonardo da Vinci also marked this union, observed especially in the illustrations of the book The divine proportionby Luca Pacioli, and the famous Vitruvian Man.

In literature, the work of the French Georges Perec, whose works are permeated with mathematical aspects, the constraints, the rules of proportion, the subtractions and even the possibility of reverse reading of his texts are inspired by mathematical elements for the construction of narratives that reflect the complex structures of human life.

Not far from this relationship between numbers and art, the mathematician and data scientist David Cecchini has worked to translate the ideas, constraints and rules present in the mind of T. Greguol into the language of the exact sciences.

The two met during their childhood, in a Waldorf school, which has as one of its bases the artistic development of students. “Our school emphasized a lot the arts, including music, as an essential part of education. Despite this influence, I developed a special interest in mathematics, the way it was taught, with playful and historical elements, going beyond numbers and formulas,” Cecchini says.

While exchanging information, the friends realized that the composition would not only fit an equation, but a theorem, which they called “Theorem BOOM”. T. says that the formula created by four hands can serve as a model for creating other pieces, which, while following the same rules, will result in different works.

Cecchini created what in his field is called mathematical modeling. And this involves converting systems or phenomena into formulas. For him, the developed rule is more than a simple theorem that represents the conception of an idea.

“This is not a software or a device that automatically performs tasks, it was created to stimulate the creative process. By inserting conditions into this system, so to speak, the artist actively participates, transforming and shaping the development. In my opinion, this capacity for involvement and creation is something that, to date, machines have not yet managed to replicate,” says the mathematician.

Instrumental work

The album made by T. is part of a specific moment in his career, in which he says he felt the need to create with abstraction, without the figurative use of words. The artist grew up in a house of six people, where television was superfluous and music was always present. His parents and his older brothers, with their different musical tastes, were the first references for him and his twin sister.

After publishing a book of poems in 2002, T. Greguol wanted to explore new forms of artistic expression. He transformed some of his texts into songs, with the help of friends and theater actors. “It was then that I realized that of the 60 poems in the book, only the eight converted into songs and included on a CD were known,” he recalls.

The journey led him to form his own band, Catarse, whose nearly decade-long career included four albums, tours, and appearances on MTV. In 2009, with the band’s demise, T. decided to put music on hold.

Eventually, T. realized that his career as a musician was involved in a struggle against the figurative use of words. He decided that his next work would be free from them. Thus began the collection Silencefocused on fine art. “These are paintings that have nothing figurative, no words, no images, nothing. It’s just pure abstraction. And in this spirit of abstraction, I came up with the idea of ​​making an album of instrumental music,” he says.

Currently, the artist says he wants to create something new and innovative, that is not necessarily popular or commercial. “I started to see music and visual arts differently, focusing on what I appreciate about them. I realized that I appreciate innovation, because repeating the same process prevents the evolution of art, of creating something new, and makes it meaningless. I’m not saying I come from the future, but there are things that take time for people to understand. So, I like to bring new things to people”, he analyzes.
