I like this idea. Here's another thought to throw into the mix, more of an
enhancement idea for the current way voices are stacked. What about
something like this:
%%%%%%%%
\version "2.19.36"
% This command takes an integer and derives the stem direction from its
% sign and then calculates the currently expected zero-based voice index
% so that 1, 2, 3, 4, etc. represent the 1st, 2nd, 3rd, 4th up-stem voices
% respectively and -1, -2, -3, etc. represent the 1st, 2nd, and 3rd down-
% stem voices, respectively.
% The integer also represents the voice's relative column priority for being
% shifted away from the principal column (i.e., larger numbers get pushed
% farther out). Positive integer voices get shifted right, negative integer
% voices get shifted left.
voice = #(define-music-function (nbr) (number?)
(let* ((dir (/ (abs nbr) nbr))
(idx (+ (* 2 dir (- nbr dir)) (/ (- 1 dir) 2)))
)
(format #t "Voice input: ~a, direction: ~a, index: ~a" nbr dir
idx)(newline)
(context-spec-music (make-voice-props-set idx) 'Voice)))
% and now an example
\new Staff <<
{ \voice 1 c''4 c'' c'' c'' } % what we know as \voiceOne, so no
difference here
\\
{ \voice 5 a'2. g'4 } % what we would call \voiceNine, if there was such
a thing
\\
{ \voice -11 g'2 b' } % what we would call \voiceTwentyTwo, but seriously
folks...
>>
%%%%%%%%
This doesn't really change the above discussion about implicit voicing and
how they should stack, but it does make it a little easier to create any
number of explicit directional voices. I guess I'm too used to the current
way of stacking. Pardon the noise if this doesn't contribute constructively
to the discussion. It was just a thought I had yesterday that I finally got
around to implementing.
Best,
Abraham
