Abstract: A system for creating and editing documents may include a reference view function which allows a user to quickly and easily refer to data that may not be included in a document. The inventive system may also include a function for saving and restoring view configurations to ensure that valuable ideas may be stored and recalled, and/or a function for tracking of motivic re-use of data.

Abstract: The present invention enables non-musicians to effectively compose music using a computer, and provides them with the means to manipulate musical content in an intuitive fashion without the need for formal musical training. The invention combines a representation of musical knowledge with a representation of musical data in such a way that permits transposition of the data to be constrained to conform to a set of harmonic rules. The user can select pitches to be moved higher or lower, and a system insures that it sounds good (where good is defined to mean "satisfies the conditions of the harmonic rule base").
