Parsons code - Wikipedia

"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 — movements 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 easier to index or search for pieces, particularly when the notes values are unknown. (...)

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:

- * = first tone as reference,
- u = "up", for when the note is higher than the previous note,
- d = "down", for when the note is lower than the previous note,
- r = "repeat", for when the note has the same pitch as the previous note.
