SYMMETRIC DODECAPHONIC HARMONY MUSIC NOTATION SYSTEM

Abstract

The present invention relates to a symmetrical dodecaphonic harmony notation system for 12 ET based music, abbreviated as SymD notation. One of the most predominant characteristics of SymD notation is a staff of 5 lines arranged symmetrically with 8 space settings between and beside the lines for all 12 semitones and its octave in a 12 ET scale. The staff serves as a visual reference for intervallic harmony relationships in sonority and melody progressions in 12 ET music.

Claims

15. A method of using the music staff of claim 1 for visually representing a piece of music in 12 ET system in SymD notation, comprising steps of: a) providing a unit staff of claim 1, numbering the thirteen unique locations including five on the lines and eight in the spaces consecutively, starting from a outside space, with location 0 for the first outside Space, location 1 for the first peripheral Line, location 2 for the first outer Space, location 3 for the first inner Space, location 4 for the first line in the middle Line group, location 5 for the first Space in the middle line group, location 6 for the center Line, location 7 for the second Space in the middle line group, location 8 for the third Line in the middle line group, location 9 for the second inner Space, location 10 for the second outer Space, location 11 for the second peripheral Line and location 12/0′ for the second outside Space; b) with respect to a piece of music, determining music notes corresponding to said music's tones in terms of intervals to the music's tonic tone, along with each tone's inception time, then assigning the note for tonic unison to location 0, minor second to location 1, major second to location 2, minor third to location 3, major third to location 4, fourth to location 5, tritone to location 6, fifth to location 7, minor sixth to location 8, major sixth to location 9, minor seventh to location 10, major seventh to location 11, and octave of tonic to location 12/0′; c) extending the unit staff lines along a time axis and putting the determined music notes at their inception times on the staff at their locations assigned in Step b).

16. A computer executable program for notating music sounds based on the method of claim 5, comprising computer instructions for steps of: (a) obtaining a first data set of music sounds; (b) extracting a second data set of music notes and time index of incepting times from the first data set by recognizing each of 12 ET tones in the music sounds at its incepting time; (c) generating a third data set of notation data by notating the music notes in the second data along with their time index, using the method of claim 5; and (d) converting the third data set into an image of music score in SymD notation.

17. A automatic program for playing musical scores in SymD notation based on the method of claim 5, comprising: (a) obtaining an image file of a musical score in SymD notation; (b) generating a data set of 12 ET notes and their inception time by recognizing these information from the image file according to the method of claim 5; (c) producing a sound file electronically or physically by generating 12 ET pitches on their inception times corresponding to the recognized information in the data set in step (b).

18. A method for converting a musical score into a score in SymD notation based on the method of claim 5, comprising: (a) obtaining a first data set from a file of a musical score; (b) extracting a second data set of 12 ET notes and their time index of inception by recognizing these note information in the first data set according to said musical score's notation rule; (c) generating a third data set of notation data by representing the 12 ET notes along with their time index in the second data set, in SymD notation using the method of claim 5; and (d) converting the notation data in the third data set of Step (c) into an image of music score in SymD notation.

Description

[0128] In conclusion, the present SymD notation system provides a visible framework for a dynamic harmony space with 12 ET intervallic symmetry. SymD notation can serve as a visual harmonic reference for all 12 ET music scores, such as diatonic tonal music, non-centric diatonic music with floating tonality, non-diatonic centric music, or atonal music.
