用图模型生成吉他和弦音即兴线路，助学生轻松练习爵士即兴。
A Graph Engine for Guitar Chord-Tone Soloing Education
- 构建加权图，节点为和弦音琶音，边权衡量转换流畅度。
- 通过最短路径算法生成符合和声逻辑的即兴演奏线路。
- 设计友好界面，方便学生输入和弦进行并获取练习建议。
我们提出一种基于图的引擎，用于为吉他学习者生成和弦音即兴建议。和弦音即兴是爵士吉他即兴的核心基础，演奏者仅使用当前和弦内的音符。该技能虽重要但难掌握。首先，我们讨论生成和弦音琶音的方法；接着，构建一个加权图，其中每个节点代表进行中某一和弦的和弦音琶音；然后，根据最优转换音计算相邻和弦节点间的边权；再通过求解最短路径，重构出一条连贯的和弦音即兴线路；最后，我们设计了一个用户友好的系统，支持输入和输出，帮助学生练习和弦音即兴。
原文摘要 · Abstract (English)
We present a graph-based engine for computing chord tone soloing suggestions for guitar students. Chord tone soloing is a fundamental practice for improvising over a chord progression, where the instrumentalist uses only the notes contained in the current chord. This practice is a building block for all advanced jazz guitar theory but is difficult to learn and practice. First, we discuss methods for generating chord-tone arpeggios. Next, we construct a weighted graph where each node represents a chord tone arpeggio for a chord in the progression. Then, we calculate the edge weight between each consecutive chord's nodes in terms of optimal transition tones. We then find the shortest path through this graph and reconstruct a chord-tone soloing line. Finally, we discuss a user-friendly system to handle input and output to this engine for guitar students to practice chord tone soloing.
