P'raps, but almost any American jazz musician familiar with the Real Books
seeing C/E is going to interpret that as a C triad over an E bass note rather
than as a polychord. C/e is just going to be confusing as to what you mean.
There are few of us left gigging who were seeing charts prior to 1960... many
of us were born around then. We're used to C/E as a slash chord rather than as
a poychord.
FWIW, polychords IME are usually written in the format of
C
-
E
which seems to me to be distinct enough from the slash chord. As jazz
scholarship has improved, though, chords that would formerly be written as
polychords to convey the idea quickly (E triad left hand, C triad right hand)
are now usually written with the extensions specified in various ways such as
Bb13b9 instead of a polychord of G triad over Bb7. Sometimes the extensions
are parenthesized or the chord is just written as "alt" letting the accompanist
select the notes (which they were going to do anyway). I don't see polychords
specified very often at all in the jazz repertoire I play. The Berklee chord
name nomenclature has become the de facto standard in most places in the US
thanks to the Real Books. YMMV depending on where you live and what chart
conventions you are used to.
Chord names become rather cumbersome quite quickly in Lilypond, with lots of
collisions being possible and difficulty with complicated chords with lots of
extensions. I'd like to be able to easily stack extensions and to parenthesize
them easily too, sort of:
c1:7._9+.^13 for a C7 with the #9 and 13 stacked after the chord, or
c1:7.(_9.^13) for the same thing with the extensions parenthesized. But that'd
probably be a *lot* of trouble to get into Lilypond and there are many more
pressing concerns to focus on. And I might be the only person who'd want it...
