摘要:

情感驱动的旋律和声化旨在为单条旋律生成多样化的和声以传达预期情感。先前的研究发现,仅通过用不同和弦对同一旋律进行和声化,很难改变主旋律谱的感知情感效价,这可能归因于旋律本身施加的约束以及现有音乐表示的局限性。在本文中,我们提出了一种用于符号音乐的新型功能表示。这种新方法将音乐调性纳入考量,认识到其通过大小调调性在塑造音乐情感特征方面的重要作用。它还允许针对调性进行旋律变奏,并解决了数据稀缺问题,以实现更好的情感建模。我们采用 Transformer 对调性可适应的旋律进行和声化,允许以基于规则或基于模型的方式确定调性。实验结果证实了我们的新表示在生成调性感知和声方面的有效性,客观和主观评估肯定了我们的方法在为多功能旋律传达特定效价方面的潜力。

英文摘要:

Emotion-driven melody harmonization aims to generate diverse harmonies for a single melody to convey desired emotions. Previous research found it hard to alter the perceived emotional valence of lead sheets only by harmonizing the same melody with different chords, which may be attributed to the constraints imposed by the melody itself and the limitation of existing music representation. In this paper, we propose a novel functional representation for symbolic music. This new method takes musical keys into account, recognizing their significant role in shaping music's emotional character through major-minor tonality. It also allows for melodic variation with respect to keys and addresses the problem of data scarcity for better emotion modeling. A Transformer is employed to harmonize key-adaptable melodies, allowing for keys determined in rule-based or model-based manner. Experimental results confirm the effectiveness of our new representation in generating key-aware harmonies, with objective and subjective evaluations affirming the potential of our approach to convey specific valence for versatile melody.
