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 analyzing patterns within a series of notes of linear musical parts, the method comprising:
analyzing, via a processing device, a plurality of repeating rhythms within one or more individual parts; storing, via the processing device, the plurality of repeating rhythms as a sequence of integers that represent note lengths of the plurality of repeating rhythms in a plurality of rhythm sequence data structures; analyzing, via the processing device, the movement patterns of the musical parts to determine shapes of musical motifs; identifying a plurality of pitch ranges for the musical parts; and populating, via the processing device, each note in the plurality of rhythm sequence data structures with possible pitches bounded by a given one of the plurality of pitch ranges based on a line in which the note lies.
