Abstract: Methods and apparatus are provided for interactively creating new arrangements of prerecorded musical works. The musical work is represented on a digital medium in the form of a database comprising a plurality of fixed musical sequences, and a template comprising a plurality of sequence positions. Each sequence position may represent one track of a musical arrangement, such as the performance of one instrumental group, or a musical solo. The various tracks are intended to be played simultaneously, in parallel. In addition, some of the sequence positions may represent fixed-length, partial segments of a single track that are intended to be played serially. Using a menu-driven, graphical interface, a user interactively selects a plurality of the fixed musical sequences, as desired, and allocates the selected sequences among the various fixed sequence positions specified by the template.
