MusicEmo: transformer-based intelligent approach towards music emotion generation and recognition

The paper proposes a novel approach called MusicEmo, a transformer-based intelligent system for music emotion generation and recognition. The paper highlights the challenges of creating emotionally resonant music that is musically cohesive and diverse. The proposed approach addresses this challenge by introducing a theme-based conditioning approach, which trains the transformer to manifest the conditioning sequence as thematic material that appears multiple times in the generated result. The MusicEmo architecture incorporates an emotion vector and an LSTM model for creating symbolic musical sequences that are musically coherent and emotionally resonant. The proposed framework outperforms state-of-the-art approaches based on musical consistency and emotional resonance. The transformer-based approach offers a fresh and original way of creating music based on emotions, and it can potentially revolutionize how we create and experience music in the future.
