Abstract:
1. A method for electronic analysis and pitch correction of a note of equal tempered tuning comprising comparing the note to a record of a small number of preceding notes in memory, where among the preceding notes there occurs a note four or six, but not five semitone steps below the analyzed note, or where a preceding note in memory transposed any number of octaves up or down, occurs a note four or six, but not five semitone steps below the analyzed note, the analyzed note, for the purpose of detecting and emphasizing a supposed inherent direction for its resolution in a harmonic progression is given an assignment of a major seventh in a harmonic context, and given a slightly raised pitch, or where among the preceding notes occurs a note three or five, but not four semitone steps below the analyzed note, or where a preceding note in memory transposed any number of octaves up or down, occurs a note three or five, but note four semitone steps below the analyzed note, the analyzed note, for the purpose of detecting and emphasizing a supposed inherent direction for its resolution in a harmonic progression is given an assignment of a minor third or a minor seventh in a harmonic context, and given a slightly lowered pitch, or where among the preceding notes occur two notes, four and five semitone steps below the analyzed note, or two preceding notes in memory, transposed any number of octaves up or down, occurs a note four and five semitone steps below the analyzed note, the analyzed note, for the purpose of detecting and emphasizing a supposed inherent direction for its resolution in a harmonic progression is given an assignment of a major third in the harmonic context and given a slightly raised pitch, wherein Analysis of a note to be pitch-corrected by comparing it to the record of a small number of preceding notes and their tunings, where among these preceding notes there occurs a note twelve (12) semitone steps below the analyzed note, the analyzed note is determined to be a perfect octave and given a slightly raised pitch relative to the pitch of the preceding note twelve (12) semitone steps below, or
