==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: *<nowiki>*</nowiki> = 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.
==Directory of Tunes and Musical Themes== Denys Parsons (father of Alan Parsons<ref>{{Cite web|url=http://alanparsons.com/artists-posts/alanparsons/|title=Alan Parsons biography|website=Alanparsons.com|access-date=21 September 2022|archive-date=18 September 2019|archive-url=https://web.archive.org/web/20190918093350/http://alanparsons.com/artists-posts/alanparsons/|url-status=dead}}</ref>) developed the 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. Parsons covered around 15,000 classical, popular and folk pieces in his dictionary. In the process he found out that *UU is the most popular opening contour, used in 23% of all the themes, something that applies to all the genres.<ref>{{Cite conference |last1=Uitdenbogerd |first1=Alexandra L. |last2=Yap |first2=Yaw Wah |date=January 2003 |title=Was Parsons right?

An earlier, alternative method of classifying and indexing melody was devised by Harold Barlow and Sam Morgenstern in ''A Dictionary of Musical Themes'' (1950).<ref>{{Cite web |last=Abbott |first=John |date=11 June 2014 |title=A Dictionary of Musical Themes: Morgenstern and Barlow (1950) |url=https://atuneadayblogdotcom.wordpress.com/2014/06/11/a-dictionary-of-musical-themes-morgenstern-and-barlow-1950/ |website=A Tune a Day}}</ref>
The ''Directory of Tunes and Musical Themes'' was also published in Germany in 2002 and reissued by Piatkus in 2008 as the ''Directory of Classical Themes''.<ref>{{harvnb|Parsons|2008}}</ref>
