A good accent notehead in LilyPond

A couple of weeks ago Max took up the challenge of making a good accent-shaped notehead. I first mailed the list back in April last year and then Jamie brought the request up again in February. Max did some pretty amazing stuff. He got the stems to center horizontally on the glyph, both up and down. And he and Jamie convinced me that a calligraphic version of glyph with thicker lower edge actually worked better than versions that were completely symmetric across the x-axis. Here are some of different variations we tried. Max cooked all these up and Jamie and I kept going through the different combinations.





And here's the final version. The trick wound up being that the calligraphic glyph had to rise just above center to make the vertical spacing work right.




This work patched into 2.11.22. And so now we have the right glyph for a tongue-ram.
