AI总结:

本文提出一种结构感知的钢琴伴奏生成方法,通过风格规划和数据集对齐的模式检索实现多样化的伴奏生成。

摘要:

我们介绍了一种结构感知的符号钢琴伴奏方法,该方法将高层规划与音符级实现解耦。一个轻量级的变压器预测一个可解释的、每小节风格计划,该计划基于段落/短语结构和功能性和声。然后一个检索器从语料库中选择并重新和声人类演奏的钢琴模式。我们将检索公式化为在显式能量下的模式匹配,包含和声可行性、结构角色兼容性、声部连续性、风格偏好和重复控制等术语。给定一个结构化的主旋律谱和可选关键词提示,系统生成钢琴伴奏MIDI。在我们的实验中,变压器风格规划引导的检索产生了多样化的长篇伴奏,具有强风格表现。我们进一步分析规划的消融实验并量化跨风格隔离。实验结果展示了我们的推理时间方法在钢琴伴奏生成中的有效性。

英文摘要:

We introduce a structure-aware approach for symbolic piano accompaniment that decouples high-level planning from note-level realization. A lightweight transformer predicts an interpretable, per-measure style plan conditioned on section/phrase structure and functional harmony, and a retriever then selects and reharmonizes human-performed piano patterns from a corpus. We formulate retrieval as pattern matching under an explicit energy with terms for harmonic feasibility, structural-role compatibility, voice-leading continuity, style preferences, and repetition control. Given a structured lead sheet and optional keyword prompts, the system generates piano-accompaniment MIDI. In our experiments, transformer style-planner-guided retrieval produces diverse long-form accompaniments with strong style realization. We further analyze planner ablations and quantify inter-style isolation. Experimental results demonstrate the effectiveness of our inference-time approach for piano accompaniment generation.
