일렉기타 벤딩 기법의 표기 체계 내 시각적 개선 연구 : 디지털 음악 산업의 연주 데이터 표준화를 중심으로 = A Study on the Improvement of the Visual Notation System for Electric-Guitar Bending Techniques : Focusing on the Standardization of Performance Data in the Digital Music Industry

다국어 초록 (Multilingual Abstract)

This study quantitatively analyzed the actual pitch variations of electric guitar bending techniques to evaluate the accuracy and expressive limitations of current tablature notation. Using the pYin algorithm in Sonic Visualiser, pitch data were extracted from guitar solo tracks and compared with bending notations in published scores. In-depth interviews with 11 experts were also conducted to assess the applicability of the proposed notation system. Results showed that conventional notation does not fully capture expressive factors such as microtonal variation and bending speed. To address this, a new notation system was proposed that visually integrates pitch trajectory and temporal flow, utilizing arrow curvature to represent bending speed and dotted lines for subtle pitch variations. Expert feedback confirmed that the system enhances accuracy and clarity while maintaining compatibility with existing tablature conventions. This study presents a new analytical perspective on guitar tablature notation and provides a foundation for its application in guitar education, digital score production, and AI-based performance analysis.
