Problems solved by technology

[0002] Past attempts at generating music software generally fall into two categories: those whose musical output does not include the level of structure required to make the music enjoyable for the listener, because such software does not apply the rules and constraints necessary to produce such structure to the output; The other is to incorporate structures into the output using hard-coded rules and constraints, which result in outputs that are predictable and lack the musical quality and variation found in human-composed music

example 1

[0175] Example 1: Fixed beat strength based on sections

[0176]In this case, each 4 / 4 bar has the same sequence of beat intensities, usually the first beat (frame 1) has a value (eg 0) and the 3rd quarter note beat (frame 9) has A value (such as 1), a value (such as 2) for the 2nd quarter-note beat and a 4th quarter-note beat (frames 5 and 13), with the same sequence of sixteenth notes in between ( In this case 4 3 4). This will make each bar have a sequence like this (intensity scale 0 to 4, with 0 being the "strongest" beat):

[0177] 0 4 3 4 2 4 3 4 1 4 3 4 2 4 3 4

[0178] This is to reflect the fact that, for the four quarter-note beats of bar 4 / 4, the rhythmic intensities are as follows:

[0179] Strong(0) Weak(2) Semi-strong(1) Weak(2)

example 2

[0180] Example 2: Hyper Beat Intensity (Super BS)

[0181] This is a combination of the aforementioned beat strength (fixed beat strength) with the concept that each bar has its own overall strength value. The result is that each frame's beat intensity value is adjusted due to the effect of "beat intensity". In particular, the first frame of each section is changed to be equal to the section strength of that section, and the remaining frames are also adjusted.

[0182] For example, the knot strength for an 8-knot cycle could be:

[0183]

[0184] Using the following method, the resulting hyperbeat intensity for each frame in the first section is thus:

[0185]

[0186] The reasoning for this hyperbeat strength will now be explained. In other words, in addition to beat strength within individual bars, the concept of section strength or "bar strength" is introduced, extending the concept of beat strength to the bars themselves. For example, the same idea could be appli...

Abstract

A computer-implemented method of generating a piece of music is disclosed. The method comprises the steps of determining an initial sequence of notes for the piece of music; determining at least one probability distribution for selecting at least one subsequent note from a set of candidate notes; generating a biasing output based on data of the initial sequence of notes; and extending the initialsequence of notes with at least one subsequent note selected from the set of candidate notes according to the probability distribution and the biasing output, wherein the biasing output biases the selection so as to affect the likelihood of the selection resulting in a repeat of a musical element formed by the initial sequence of notes.

Description

technical field [0001] The present disclosure relates to a computer-implemented method of generating pieces of music. Background technique [0002] Past attempts at generating music software generally fall into two categories: those whose musical output does not include the level of structure required to make the music enjoyable for the listener, because such software does not apply the rules and constraints necessary to produce such structure to the output; The other is to incorporate a structure to the output using hard-coded rules and constraints, which results in an output that is predictable and lacks the musical quality and variation found in human-composed music. [0003] There is a need for methods for generating more complex and aurally pleasing music, characterized by longer ranges of repeats and patterns, but which preserve the avoidance of hardcoding the output A system of rules and constraints for musical quality and variation.
