thanks indeed Stephen, its a nice idea to lump the
chord symbols into "one" rather
than do a \markup to all notes. The Vb is just the
first inversion of the chord, the b is not
a flat symbol.
I guess one thing that puzzled me with the \override
TextScript.padding is why the outcome didn't just add an further offset
but with the same result of the symbols going up and down following the
music.
Perhaps \override means not only override the default
offset, but turn off completely the following
of the music ?
