We propose different methods for alternative representation and visual augmentation of sheet music that help users gain an overview of general structure, repeating patterns, and the similarity of segments. To this end, we explored mapping the overall similarity between sections or bars to colors. For these mappings, we use dimensionality reduction or clustering to assign similar segments to similar colors and vice versa. To provide a better overview, we further designed simplified music notation representations, including hierarchical and compressed encodings. These overviews allow users to display whole pieces more compactly on a single screen without clutter and to find and navigate to distant segments more quickly. Our preliminary evaluation with guitarists and tablature shows that our design supports users in tasks such as analyzing structure, finding repetitions, and determining the similarity of specific segments to others.

翻译：我们提出了多种替代表示与视觉增强乐谱的方法，帮助用户纵览整体结构、重复模式及乐段相似性。为此，我们探索了将乐段或小节之间的整体相似性映射至颜色的技术路径。在颜色映射中，我们采用降维或聚类方法，使相似乐段获得相近颜色，反之亦然。为提供更优的全局视图，我们进一步设计了简化的乐谱表示方案，包括层级编码与压缩编码。这些概述性视图使用户能够在一屏之内更紧凑地呈现完整曲目而避免杂乱，并更快速地定位与导航至相距较远的乐段。我们针对吉他演奏者与六线谱的初步评估表明，该设计能有效支持用户完成结构分析、重复模式查找以及特定乐段与其他乐段相似性判定等任务。
