 note = {音高（ピッチ）はその相互の音程関係において循環性や協和といった心理的特質を持ち，全音階をはじめとする音階や和声に関する理論が音楽理論として構築されてきた．従来のピッチ表記法や符号化方式は，音名・階名やオクターブを記号や数字に置き換えただけの表現にとどまっており，数量的な評価という観点では必ずしも便利ではない．本発表ではピッチ表記法同士や記数法との比較を通じて音高の量的表現を議論し，位取り記数法と同じ方式で数値化される十二進位取りピッチ表記法を提案する．考察の題材としてピッチの音響心理学的モデルや音楽理論における概念および操作を取り上げ，提案手法による表現の有効性と可能性を検討する．, Pitch has psychological attributes such as cyclicity and consonance in its mutual interval relationships, therefore musical theory has been constructed as a study of scales including the diatonic scale and harmonies. Traditional pitch notation and encoding systems have been limited to representations that merely replace note names, scale names, and octaves with symbols or numbers, which might not be always convenient ones from the view point of quantitative evaluation. In this presentation, we discuss the quantitative representation of pitch through comparisons between different pitch notations and numeral systems, then propose a 12-based positional pitch notation system that has a value in the same way as positional numeral systems. As the subject of discussion, we explore the acoustic psychological models of pitch and concepts and operations in musical theory, considering the effectiveness and potential on representation of the proposed system.},
