Re: Custom upbow and downbow markings

Hello All,

Continuing my investigations here, with reference to the list archive:

https://lists.gnu.org/archive/html/lilypond-user/2015-04/msg00118.html

I have tried making a custom articulation, rather than a text markup, and of course, all the alignment issues are solved. MWE below.

I will now transform my question. I have copied this code idea rather blindly with little understanding. Where is there any tutorial or reference information on extending lilypond to create new articulations?

This is exactly what I was thinking yesterday after arriving at the point that my problem was solved. Adding custom articulations is a pretty obscure technique (I mean, you "hijack" one of LilyPond's built-in data structures) but I think a valid one that should be made available.

I didn't feel up to writing a tutorial yet because there are too many grey areas wrt my current level of knowledge. But we could commit to writing a tutorial post together, which would give the context and the opportunity to sort these things out.

What do you think?

Would a sampler like this be a good addition to LSR to help others out in the future?

Is my problem that this is a markup and not a proper articulation?
