Abstract

This paper introduces a way to generate or modify a melody using the editable noise function. The band-limited random numbers generated by the noise function are converted to the various property values of notes such as pitch and duration. Using this technique, we can modify an existing melody to produce new, similar melodies. The noise values can be edited, if necessary, while preserving the statistical characteristics of the noise function. By using this noise editing method, the noise function can generate a melody that satisfies given constraints.
