Expanded Authorship – Lorenzo Bosich – ASTRATALK

From the 1535 treatise to AI composing for string orchestra: three works examined and dissected to understand where the composer’s influence ends

In 1535, Silvestro Ganassi’s *La Fontegara* was published in Venice—a treatise teaching the art of diminution: how to take a musical line and fill it with smaller figures, following a repertoire of formulas and rules for combining them. Those who applied it did not improvise at random nor start from scratch: they followed a specific process. The resulting music was their own, and the question of who its author was never arose.

Five centuries later, that question has resurfaced, and this time many people are asking it: when part of a work is created through a process, what remains of the author?

In this Astratalk, Lorenzo Bosich approaches the topic from within his own work, in three stages. The first is *La Fontegara*, viewed precisely in its almost mechanical dimension. The second is composition for string orchestra with AI used as a tool: the technology becomes part of the compositional process, not an afterthought or mere effect. The third is an integrated audiovisual work, for which he explains the techniques and production process.

It’s an evening where you watch a work being taken apart. There’s no argument to be made about whether AI replaces or doesn’t replace the creator, and there are no set formulas: there’s a composer showing how he works now—what he decides, what the instrument suggests, and what ends up being discarded. The material is musical, but the process is recognizable even from the outside: the same question arises for writers, designers, and programmers when they’re working with something that offers its own suggestions.
