A completely different notation approach might be more economic from a
pure notation point of view (many have been proposed), but musicians
including myself just had a life-long training in the existing
notation. So, for those an extended form of the existing notation is
more appealing than something that starts form scratch.
Strictly speaking, it depends on which music instrument you have.
Mine is a 2-dimensional keyboard.
If your notation depends on your instrument then you devised actually
a tabulature. They have their purposes of course, but being instrument
specific they have their restrictions too. BTW: I can actually play HE
notation on a Tonal Plexus (http://www.h-pi.com/TPX28intro.html),
slowly, but I never practise :)
Best

This uniform structure of the Helmholtz-Ellis and Sagittal notation
makes it possible to not only notate just intonation but also
arbitrary equal temperaments (equal divisions of the octave) with
them. The example below shows the pitches of 41-tone equal
temperament with Helmholtz-Ellis notation. Note that other
enharmonic pitches are possible, for example, Db and C#L (C#
transposed down by a septimal comma) share the same 41-tone equal
temperament pitch class (namely pitch class 3, the fourth note
below).
Yes, but I tend to think that ETs and Pythagorean tuning, quarter-
comma meantone, and other diatonic pitch systems would be best
notated by departing from them, and then adding intermediate pitch
accidentals relative that. Strictly speaking, it depends on which
music instrument you have. Mine is a 2-dimensional keyboard. I
figured it would take too much work learning new playing pattern for
each tuning, especially in rapind movements, ornamentation, etc. I
do not know of a good way to play intermediate pitches yet, though.
I think this way of notating should be possible with the system I
described in my other mail.
Hans
