让音乐循环搜索变创作工具，支持自由拼贴式作曲
LoopLens: Supporting Search as Creation in Loop-Based Music Composition
- 用多模态可视化辅助用户在音乐循环中探索与组合
- 有经验者快速锁定少数循环，无经验者广泛试听受限于词汇量
- 适合音乐创作新手或想突破创意瓶颈的创作者
创意支持工具通常将搜索视为信息检索，但在电子舞曲制作等实践中，搜索本身是拼贴式创作的媒介。为此，我们提出LoopLens，一种针对循环音乐创作的研究探针，通过可视化音频搜索结果，支持创造性探索与组合。我们在16名不同音乐背景的参与者中开展包含开放式（发散）和目标导向（收敛）任务的自身对照实验。结果显示显著的行为分化：具备领域知识的用户利用多模态线索快速聚焦于少数循环，而缺乏知识者主要依赖听觉印象，进行广泛探索，但常受限于查询表述的音乐词汇量。这一行为二分法为理解创作搜索中的探索与利用平衡提供了新视角，并为未来支持词汇无关发现的创意工具设计提供了明确启示。
原文摘要 · Abstract (English)
Creativity support tools (CSTs) typically frame search as information retrieval, yet in practices like electronic dance music production, search serves as a creative medium for collage-style composition. To address this gap, we present LoopLens, a research probe for loop-based music composition that visualizes audio search results to support creative foraging and assembling. We evaluated LoopLens in a within-subject user study with 16 participants of diverse musical domain expertise, performing both open-ended (divergent) and goal-directed (convergent) tasks. Our results reveal a clear behavioral split: participants with domain expertise leveraged multimodal cues to quickly exploit a narrow set of loops, while those without domain knowledge relied primarily on audio impressions, engaging in broad exploration often constrained by limited musical vocabulary for query formulation. This behavioral dichotomy provides a new lens for understanding the balance between exploration and exploitation in creative search and offers clear design implications for supporting vocabulary-independent discovery in future CSTs.
