Creating music and sound that varies from playback to playback

A method for creating a music or sound composition, comprising:

• providing or creating at least one foundation sound segment;
• providing or creating a plurality of overlaying sound segments, wherein an overlaying sound segment at least partially overlays a foundation sound segment;
• mixing together different subsets of said overlaying segments with said at least one foundation segment, to create a plurality of alternative mixed sound segments representing different playback versions;
• providing or creating, a playback dataset, that is to be automatically processed during later playback, wherein during later playback, the dataset causes at least one of said alternative mixed sound segments to be automatically selected without user action;
• wherein the alternative mixed segment or segments that are selected differs from one playback to another playback;
• and
• storing said segments and dataset, to allow said dataset to be automatically processed at a later time to form a sound sequence that varies from one playback to another playback without requiring user action to cause said variation.

A method for creating a music or sound composition, comprising:

• storing into a memory or memories, a plurality of alternative sound segments that are:
• created, by an artist or artists, substantially simultaneously with creating a foundation sound segment by the artist or artists;
• and/or
• created, by an artist or artists, substantially simultaneously with, an audio playback to the artist or artists, of a previously recorded foundation sound segment;
• creating a playback dataset, that is to be automatically processed during later playback;
• wherein the playback dataset causes at least one of the alternative sound segments to be selected and combined with at least one of the foundation sound segments;
• wherein the selection of the alternative sound segments varies from one playback to another playback without requiring user action to cause said variation;
• and
• storing said segments and dataset, to allow said dataset to be automatically processed at a later time to form a sound sequence that varies from one playback to another playback without requiring user action to cause said variation.

An apparatus implemented method for creating a music or sound composition, comprising:

• displaying, on an electronic display, representations for a plurality of sound segments that are created-by or input-into the apparatus;
• wherein the representation of an individual sound segment indicates a time location and a time duration of the individual sound segment;
• responding to user actions that select or interact-with individual sound segments displayed on the electronic display to define a variable selection of at least of one sound segment from a plurality of alternative sound segments;
• wherein the variable selection differs from one playback to another playback;
• creating a dataset, that during later playback is to be automatically processed by a playback program or processor;
• wherein when the dataset is processed during later playback, a varying subset of said alternative segments are automatically selected without requiring user action;
• wherein the alternative segments that are selected differ from one playback to another playback;
• and
• storing the dataset, in a storage memory or memories, to allow said dataset to be electronically processed at a later time to form a sound sequence that varies from one playback to another playback, without requiring user action to cause said variation.
