Hi Peter,
> Thank you so much for your response and the example code—it works beautifully
> and already gets very close to what I envisioned. I really appreciate the

> That was a creative idea I hadn’t thought of!
I pride myself on thinking outside the box… :)
> I’ve been trying to reproduce this effect using your method, tweaking
> position and transparency, but I haven’t quite managed to achieve a true
> overlay that floats behind the chords and melody without affecting spacing.
> Do you think it’s feasible to achieve such a watermark-like degree indication
> in LilyPond? Ideally, it would:
> • Appear very large and semi-transparent;
> • Overlay directly beneath or behind the chord symbol;
> • Not affect vertical spacing or push any other elements out of place;
“With Lilypond, all things are possible.”
