Work in three areas comprised this study of computer use in thematic indexing for music research: (1) acquisition, encoding, and keypunching of data--themes of which now number about 50,000 (primarily 16th Century Italian vocal music) and serve as a test base for program development; (2) development of computer programs to process this data; and (3) development of special computer typography for music printing. It is recommended that work in each of these three areas be continued as desirable and feasible in musicological research. (Appended are lists of papers and articles summarizing work on this project, samples of music typography showing incipits in interval sequence order, and a computer print-out showing composer, title, page, source, genre, and serial number.)
