When I first saw Chip's example, my reaction was "why on earth would you
want to do that?"
As I understand it, \relative converts from note names to absolute
pitches. Pretty much everything else in lily works on pitches. In a .ly
file you don't know, on seeing a "c", which c it is - middle, top, low,
whatever. If it's wrapped in a \relative{}, that assigns a pitch to it.
Anything else on seeing it assumes it's "c in the bass clef" as that's
the pitch assigned to the note "c".
So, I don't know how to word it, but when you're talking about \relative
in the manual it should say that you should only use \relative
immediately around your note names because it converts note names to
absolute pitches. If there's another operator inside your \relative (ie
in Chip's case, a \transpose, in the example above an inner \relative)
that forces absolute pitches, then the \relative will do nothing because
it doesn't know what to do with a pitch.
Cheers,
