Hallelujah! After several years of futile searching I have finally found the correct tweak to make gracenotes non-stretchable in Lilypond. Yesss!!

To celebrate this great discovery, I have regenerated all of the tunes in the Sheet music section of the site. Because of the new and improved spacing this gets me, I have also been able to reinsert a bunch of line breaks that were removed previously to make the layout suck less. Now it doesn’t suck at all!

You may or may not have noted that all the music on this site is available as Lilypond source on Github. Check out https://github.com/svenax/bagpipemusic and be amazed.
