Some time ago I wrote saying that I could not get the marking "sfffz" to kern
properly. Someone replied that it did for them, and I let it sit there,
waiting until I needed a solution, which point I have now reached. I have been
slow and dense in recognising where the issue lies - I am using the BMusicFont
(a version of Dorico's font, more recent than the "profondo" version). The
kerning works in Feta, but not in this font.
I have, however, managed an effective work-around:
sfffzX = \markup\center-align\concat{"s" \dynamic"fff" \hspace #-0.5 "z"}
sfffz = #(make-dynamic-script sfffzX)
The "s" already kerns ok, and specifying the "fff" dynamic gets the
fully-kerned version of those letters. The "z" doesn't kern nicely, but can be
pushed back to the required position.
