Automatic expressive intonation tuning system


A method for the algorithmic expressive intonation tuning (EIT) and performance of electronic, computer and MIDI musical works relies on melodic intervals, rather than on chordal harmony, and acts by desirably modifying the pitch of a note slightly (compared to equal temperament tuning), depending on the next melodic note. This dynamic, non static, melodic tuning emulates, and can even possibly augment, aspects of outstanding live human musical performance achieved with regard to pitch subtleties, as it enhances the living sounding, real aspects of the performance of electronic, computer and MIDI music, by sensibly causing a slightly different pitch of particular notes, depending on the size of an interval and on whether an interval is ascending or descending, with the same note subtly having more than one pitch often, depending on melodic context. This method of tuning affecting the notes has a further advantage of not requiring transposition, regardless of how much the music modulates, since it uses melodic intervals. It can treat entire symphonies of more than 100 voices simultaneously as easily as solo works.
