A IA consegue compor música original que imite o estilo de famosos compositores clássicos ?

Os modelos de IA conseguem agora gerar partituras orquestrais completas indistinguíveis das de Bach, Mozart ou Beethoven. Estas composições adaptam-se às regras de humor, andamento e instrumentação de cada época. Algumas IAs até enganaram audiências em testes de audição cega. Isto desafia as nossas noções de criatividade e autoria. A tecnologia está a ser usada em bandas sonoras de filmes e media interativa.

Background

AI systems today can generate short pieces that stylistically resemble works by famous classical composers such as Bach, Mozart, or Chopin, using neural networks trained on large corpora of historical scores. Models like MuseNet and transformer-based architectures can produce four-part chorales in Bach’s style or waltz-like piano pieces after Chopin. These outputs often lack the depth, coherence, and emotional nuance of human compositions. While the systems mimic surface-level stylistic features—melodic contours, harmonic progressions, and rhythmic patterns—they typically do not achieve the structural originality, thematic development, or expressive intent characteristic of canonical classical works. Outputs are generally limited in length and tend to blend features rather than produce truly novel, historically faithful compositions. Despite these limitations, some AIs have fooled audiences in blind listening tests, raising questions about creativity and authorship. The technology is also being adopted for film scoring and interactive media.
