Computerized system for imparting an expressive microstructure to succession of notes in a musical score

Claim 1

A computerized system for imparting an emotionally expressive microstructure to the respective notes in the score of a musical composition constituted by a succession of notes whose notation provides the nominal value for each note in regard to its pitch and duration, said system comprising: A. a digital calculator; B. means to enter into said calculator nominal data representing the nominal pitch and duration of each of the successive notes in the musical score to be processed; C. a matrix having stored therein microstructure data relating to the relative loudness and duration values of a series of notes forming a group representing the inner pulse of a given musical composer; D. means to enter into said calculator said microstructure data, said calculator including means to process the nominal data entered therein with reference to the microstructure data entered therein to yield in its output with respect to each note in the succession thereof a series of digital values representing loudness and duration changes in accordance with their interrelationship to said inner pulse and to contour the amplitude of each note in accordance with its relationship to the succeeding note; and E. means responsive to said output to generate and audibly reproduce tones representing the notes of said score with said microstructure data impressed thereon to render the reproduced music derived from the score expressive.
