Chord Progression and Melody Matching Based on Music Score

Abstract

Whether it is classical jazz or pop music most of the music is composed of melody and accompaniment The relationship between accompaniment and melody can be said to complement each other melody is the most obvious form of music while chord is related to the color and harmony of the music Interestingly some chord progressions are very popular Taking pop music as an example whether it is Chinese or Western songs many songs use same chord progressions For example AMei ”Remember” Faye Wong ”Red Bean” Jay Chou ”Faraway” and Maroon 5 “Memories” use IVviiiiIVIIVV chord progression (”Pachelbel’s Canon” Progression)? While Mayday ”Final Chapter” Beyond ”Really Love You? Jason Mraz “I?m Yours? OneRepublic ”Apologize” and Alan Walker ”Faded” use I–V–vi–IV chord progression (4chord song progression) and so on We are curious about whether we can combine the chord progressions of a song with the melody of other songs or modify some notes of the melody to match it This paper proposes a system that can match the melody and chord progression of different song using the lead sheet in the MusicXML format as the data set Users first specify a chord progression segment of a song in the data set Then the system rank the candidate melody segments in the data set according to the nonchord notes and rest duration and provide the option to adjust the pitch or duration of notes in the melody segments to produce more variations Finally the system rerank and output the melody result according to the similarity to the original melody We use a sequencetosequence autoencoder (objective) to calculate the similarity between melodies and apply a listening test (observation) to verify this method
