This project comprises the second year's work of a 3-year research plan to develop computer programs, necessary data, and procedures for using the computer in a special field of musicology known as thematic indexing, and to explore the use of these techniques in other areas of music. During the second year, the research centered on three areas: (1) continuation of encoding of incipits (opening theme of a piece) of 16th-century materials (This data bank, now containing more than 40,000 themes, serves as testing material for validating programs as well as providing a source of information for other musicologists.) (2) continued development of special programs for information retrieval, pattern matching, and organization of data for publication by direct photo copy of computer output, (3) development of special type faces of music symbols for use on the high speed computer printer. Preliminary tests with the new type were successful. (Appendices include examples of two stages of computer printing of music notation.) See also ED 027 609. (Author/MF)
