I’m working on a piano/vocal score right now, and I’m finding it hard to tweak the spacing values for lyrics.
In Engraving Options > Lyrics > Spacing, I’d like to be able to specify different minimum gap values for adjacent lyrics depending on how they’re separated, whether it’s a hyphen, an extender line, or nothing.
In my opinion, the distance between adjacent lyrics separated by a hyphen can be smaller than the distance between adjacent lyrics separated by a space. A smaller distance allows different syllables of a word to be spaced closer together, which not only reduces horizontal spacing pressure, but also helps with word recognition. In contrast, the distance between adjacent lyrics separated by a space should be large enough to clearly recognize a space. A single minimum gap value here must compromise between these two goals.
In addition, setting this “Minimum gap between adjacent lyrics separated by a hyphen” value to be equal to or greater than the “Minimum gap between lyric and hyphen” should guarantee the presence of a hyphen whenever they are used, and one could similarly force the presence of an extender line.
