Основные понятия
A model for generating symbolic orchestral music that can transfer the style of a reference piece while maintaining melodic fidelity and allowing control over textural attributes.
Аннотация
The paper presents METEOR, a model for Melody-aware Texture-controllable Orchestral music generation. The key points are:
-
METEOR is designed for symbolic multi-track music style transfer, allowing control over textural attributes while ensuring melodic fidelity.
-
The model provides two levels of controllability:
- Bar-level control over polyphonicity and rhythmicity
- Bar- and track-level control over average pitch and pitch diversity
-
To maintain melodic fidelity, the model identifies the melody in the reference piece and enforces it in the generated content, while allowing the choice of melodic instrument to change across bars.
-
Evaluations show that METEOR can achieve controllability performances similar to strong baselines while greatly improving melodic fidelity. The model also demonstrates the ability to associate melodic instruments with their typical register.
-
The model can perform style transfer as well as lead sheet orchestration, with audio examples available on the demo page.

"some salient features such as melodies are often not preserved" - FIGARO [6]
The average generated pitch for the cello and the violin are much lower, as much as a sixth lower than the midpoint note of the instrument's full register.
Цитаты
"Western music is often characterized by a homophonic texture, in which the musical content can be organized into a melody and an accompaniment."
"Style transfer systems often focus on the accompaniment complexity, leading to unintended alterations of the melody when adjusting control signals."
"The orchestral score can indeed be described by global characteristics such as instrument groupings or part diversity, as well as part-specific attributes such as rhythmicity or repetitiveness [3], which create the overall musical texture."
