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.
