The Parsons code, formally named the Parsons Code for Melodic Contours, is a simple notation used to identify a piece of music through melodic motion—the motion of the pitch up and down. Denys Parsons developed this system for his 1975 book, ''The Directory of Tunes and Musical Themes''. Representing a melody in this manner makes it easy to index or search for particular pieces. The book was also published in Germany in 2002 and reprinted by Piatkus as ''The Directory of Classical Themes'' in 2008. ==The code== The first note of a melody is denoted with an asterisk ( *), although some Parsons code users omit the first note. All succeeding notes are denoted with one of three letters to indicate the relationship of its pitch to the previous note: *u = "up," if the note is higher than the previous note *d = "down," if the note is lower than the previous note *r = "repeat," if the note is the same pitch as the previous note * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parsons code」の詳細全文を読む スポンサード リンク
