Abstract:
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 internal 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.

Claim (Index 17):
Non-transitory computer readable media comprising program code that when executed by a programmable processor causes execution of a method for electronically composing music, the computer readable media comprising:\n computer program code for retrieving music data blocks from a library of music data blocks, the music data blocks extracted from sequences of abstract music data from music input; computer program code for generating key and chord sequences of abstract music data by re-arranging the music data blocks into slots of a set of frames based on key and chord combination rules; computer program code for selecting a rhythm sequence from rhythm data extracted from the music input; computer program code for selecting a pitch for each note slot in the rhythm sequence based on a set of movement combination rules and the generated key and chord sequences; computer program code for composing music data based on the selected pitch for each note slot in the rhythm sequence; and computer program code for converting the music data into a music output data format file.
