This appears to be almost completely undocumented, and there are some
things I can't seem to guess/decipher.
How do "chord subtractions" work? What exactly does it mean if I
write
notename-digit
It looks like it does two things: forces the chord to have all the
notes up to and including the one specified by the digit. And also it
may raise or lower the note that is position digit in the chord.
(But this isn't quite true because c-4 eliminates the 3rd, and c-10
eliminates the 2nd)
The following produced an assertion failure and coredump (1.1.23):
\score{
\notes \transpose c''{ c \chords{ c-3- c-5+ c-^3 }}
\paper{linewidth=-1.;}
}
\relative interacts oddly with chords. I'd call it a bug: only the
tonic note is affected the the \relative.
Inversions should print a warning if the note I'm trying to invert to
isn't in the chord. (Does this note have a name? I'm not sure what
it's called.)
So for example:
c-min/e
comes out uninverted and with no warning message. There should be a
warning message.
Oh, yes, and what is the lexical difference between chord mode and
note mode?
I noticed also that @ and \chords are not equivalent.
\notes { @c-7 } is a parse error, but works in \chords{}. Is this a bug?
