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.

主权项

1. A method for analyzing frames and music data blocks of musical data, the method comprising:
receiving, via a processing device, music input data; extracting, via the processing device, an initial sequence of data from the music input data; generating, via the processing device, a plurality of music data blocks from the initial sequence of data; calculating, via the processing device, fitness scores for the plurality of music data blocks; determining, via the processing device, one or more of the plurality of music data blocks with the highest fitness scores; populating, via the processing device, slots of one or more sequence frames with placeholders that represent the one or more music data blocks with the highest fitness scores; and generating, via the processing device, one or more key, chord, harmony, rhythm and movement pattern sequences based on the one or more sequence frames.
