Abstract
In this paper I introduce a new algorithm called ps13 that reliably computes the correct pitch names (e.g., C#4, B#5 etc.) of the notes in a passage of tonal music, when given only the onset-time and MIDI note number of each note in the passage. ps13 correctly predicts the pitch names of 99.81% of the notes in a test corpus containing 41544 notes and consisting of all the pieces in the first book of J. S. Bach's Das Wohltemperirte Klavier (BWV 846--869). Three previous algorithms (those of Cambouropoulos (1996, 1998, 2002), Longuet-Higgins (1987) and Temperley (2001)) were run on the same corpus of 41544 notes. On this corpus, Cambouropoulos's algorithm made 2599 mistakes, LonguetHiggins 's algorithm made 265 mistakes and Temperley's algorithm made 122 mistakes. As ps13 made only 81 mistakes on the same corpus, this suggests that ps13 may be more robust than previous algorithms that attempt to perform the same task.
