Computer Processing of Musical Scores
This paper proposes an encoding scheme for printed music. A computerized system is designed and implemented to read music as human-encoded symbols, decode and store it within the computer, and to print it our either in its original key or in another key specified by the user. The graphics output is obtained by translating musical symbols into positional information and plotting it on a high resolution digital plotter. The rules for transposition, including those for transposing accidentals, are formalized. These have been programmed and appear to work correctly. The graphic output obtained is of high quality and should be acceptable for several purposes. The usefulness of the system would be increased immensely by providing a graphical input phase. Several plotter outputs of examples of musical scores along with the required coding are included.
