I haven't noticed any effect with polyphony: the octavation of the
next note in the source is always determined by the previous one.

Chords are different but simple: when you get to the > at the end of a
chord, the next note in the source is related to the first note of that
chord; ie in a sequence of chords, their first notes form the
\relative sequence. What gets in the way of what?

I don't understand what you mean. When you write

musa = \relative { c f a c f a c f }
musb = \relative { c g d a e c g d }

{ \clef bass \musa \musb \musb \musa }

\musa and \musb are absolute; their constituent pitches are baked in.
The pitches don't "interact" when you later combine them.

Were you to put pitches into your structures (I don't), it would
indeed be idiosyncratic to wrap it in a \relative { }, in fact...

, I'm
not sure how it would be parsed.

So your describing the score above as a hybrid seems pointless:
virtually every LP score that uses \relative anywhere would be
a hybrid in your book. About the only exceptions would be fragments

\relative { c' d e f g a b c }

I'm trying to work out what you mean by this. My only idea is that you
don't like the change in indentation level caused by transposition, as

c' d' e' f'
\transpose c c' {
g a b c'
b' a' g' f'

to which my solution would be

\absolute {
c' d' e' f'
\transpose c c' {
g a b c'
\absolute {
b' a' g' f'

so that everything is now at the same level.

I'm tired of guessing what you mean. Please just post an example and
what bugs you about it.
