Re: Appending minor chords with "sus2/sus4"

[Brent Annable]

Lukas,

Aaaah, that makes sense. As a classical stiff I just assumed that suspensions resolve downwards by default, so the 2 was in fact a suspended tonic, not a suspended third. And since the minor third is already present in the chord I'm dealing with, I think I'll just change it to Gm add9.

Thanks again!

Brent.

It's not very common to ask for Gm-sus2 oder Gm-sus4: The sus2/sus4
replace the third in the chord, so there's no trace of "minor" left.

But you speak of _added_ suspensions: This sounds to me as if you are
looking for Gm-add9 or Gm-add11?

All of these may be forced with chordNameExceptions:

\version "2.22.1"

chExceptionMusic = {
   <c f g>1-\markup { m\super "sus4" } % Semi-advisable? :-)
   <c d g>1-\markup { m\super "sus2" } % Semi-advisable? :-)

   <c es g d'>1-\markup { m\super "add9" }
   <c es g f'>1-\markup { m\super "add11" }

}

% Convert music to list and prepend to existing exceptions.
chExceptions = #(append
   (sequential-music-to-chord-exceptions chExceptionMusic #t)
   ignatzekExceptions)

exampleChords = \relative {
   <g' a d> <g c d> <g bes d a'> <g bes d c'>
}

theMusic = {
   \mark "Standard"
   \exampleChords
   \bar "||"
   \set chordNameExceptions = #chExceptions
   \mark "Custom"
   \exampleChords
}
