hm, my answer is a bit out of lilypond scope, but if I understand your question correctly, you want to understand what these chords are?
they are three different pre-dominant chords that are taught to American undergrads in a sophomore theory course.
in E major:
Italian = C E A#
French = C E F# A#
German = C E G A#
Tristan = C D# F# A#
in all of them, the C and A# in theory want to fan out to B (the dominant). This is, of course, in theory - Wagner’s use of the Tristan chord, which he clearly named his opera after, has the A# moving down to A, or the 7th of the dominant (I’m transposing to fit w/ the example above). Wagner obviously did not pay much attention during his sophomore music theory course…

Hello folks,
MusicXML supports neapolitan, italian, german, french and tristan chords, i.e.:
<harmony>
<root>
<root-step>C</root-step>
</root>
<kind>Neapolitan</kind>
</harmony>
I’ve found information about neapolitan, but nothing about the others.
What is the structure of those?
Thanks!
JM
