System and method for analysis and creation of music

摘要

A method and system for analyzing patterns in the relationships of notes of an input piece of music. The method comprises generating a set of the most frequently occurring note pitches in ascending pitch order that matches an interval pattern, and detecting out-of-key pitches that lie outside of this interval pattern. One or more potential key sequence bifurcations are identified which represent a list of possible key sequences according to forwards and backwards analysis. By finding patterns of repetition in the chordal sequences that may be generated according to these key sequence bifurcations, a key sequence that allows the most frequently recurring chord sequences may be chosen. Chord sequences may be analyzed by using ghost chords, temporary harmonic structures that are created, updated and finalized over time according to a combination of essential and inessential note fragments. The method further comprises identifying non-harmony pitches according to the analyzed chord sequence.

1. A method for generating sequences of abstract musical data, the method comprising:
extracting, via a processing device, music data blocks from sequences of abstract music data from a music input; identifying, via the processing device, frames of repetition from the sequences of abstract music data; selecting, via the processing device, a set of frames independent of part; re-arranging, via the processing device, the music data blocks into slots of the set of frames based on key and chord combination rules to create new sequences of abstract music data; composing, via the processing device, new music data based on the new sequences of abstract music data; and converting, via the processing device, the new music data into a music output data format file.
