Re: Making espressivo longer

[Andrew Bernard]

Hi Ben,

Yes this is the code in the list archives that I was referring to in my initial mail. My question was actually not so much how to achieve this, but whether a technique for this has been incorporated into lilypond more recently, similar to how hairpins can now be adjusted with the shorten-pair technique common to other objects.

The problem I have with this code is that, finding that it works, I altered it to allow scaling in the vertical axis as well, but that is highly unsatisfactory as the line width gets scaled as well - perhaps why the code omitted that feature to begin with.

Espressivo marks are just hairpin-like objects, and I suppose I can just revert to using hairpins, but it's a bit annoying as you have to make a separate voice for the hairpins to start and finish on non-existent notes.

This is one of those lilypond things where you give a person an inch and they want a mile!

What is the current best practice for scaling espressivo indicators, making them longer?

There's a scale function in the archives from Harm, but I wonder if there is a mechanism built in to 2.19.82 and so on?

Hi Andrew,

I had asked that question a while back on the mailing list in 2013, and I've still been using this - it's worked fine so far - fwiw.

Not sure if another approach exists but so far so good here :)
