Revealing Focusing Points for Piano Instruction through Performance-Evaluation Analyses

To develop an effective piano instruction method, factors that affect the evaluation of piano performance were quantitively analyzed. Three judges evaluated performances by piano students. In addition to an overall evaluation (impression), four factors (correctness, rhythm, tempo, and musical flow) were individually evaluated. The obtained evaluation scores were analyzed with a multiple regression analysis. The results showed that, of the four individual factors, musical flow and rhythm had a more significant impact on the overall evaluation. For the group who received low overall evaluations, rhythm had the most impact on the overall evaluation, and for the group who received high overall evaluations, musical flow had the most impact on the overall evaluation. The focusing points for piano instruction were thus shown to be different, depending on students' learning stages.効率的なピアノ教授法の開発を目指し、本研究ではピアノ学習者の演奏評価に影響を与える要素の定量的解析を行った。保育士・教員養成校のピアノ学習者を対象にした初見演奏を3 名の審査員で評価した。評価は4つの要素（音の正しさ、リズム、テンポの一定さ、曲の流れ）の評価と演奏評価（印象点）とで行った。重回帰分析の結果、曲の流れとリズムが演奏評価に強く影響を及ぼしていることが示された。さらに、演奏評価が低いグループは、リズムの評価が演奏評価に強い影響を与え、演奏評価が高いグループは曲の流れが演奏評価に強い影響を及ぼしていることが明らかになった。従って、ピアノ指導ポイントは、学習者の習得段階によって異なることが示された。departmental bulletin pape
