Method and apparatus for computer-aided variation of music and other sequences, including variation by chaotic mapping

摘要

An altered but recognizable variant of an input musical composition is created by parsing the input into elements, selecting elements for replacement using a hole-selecting algorithm, and replacing the selected elements using a substitution algorithm. A plurality of tracks from the same composition, or from different compositions, can be separately varied and combined, or concatenated and varied together, or used as a seed source of a substitution algorithm, to create a remix or mash-up. Music variants can be combined with photographs, images, or videos, for distribution to recipients, or for a project presentation or story board. Greeting cards, MP3 players, mobile electronic devices, wearable electronic devices, toys, video games, websites, and ringtones can be configured to create and play a new variant of an input composition each time it is accessed. Websites can be used to host and track successive, “chain” variations of an input musical composition.
