Hello: I'm constantly working on my piece for large orchestra and mixed chorus. It's very slow to compose using Lilypond. I'm now encountering a passage quoting a folk song of my place, with many special ornaments. In Chinese music, there are many glissando "tail"s after long notes. I searched the new glossary just now, and found the explanation for Doit and Fall are out. But I can't see the actual signs, and my mother is not familiar with full score and the special clef I use for this passage (the second percussionist blows the leaf, so I use an 8va G clef). The problem is, do fall and doit mean sliding away immediately or after a while (like gliss on a long note)? I now have to do a lot of hide/unhide note to approach it, but I think the spacing may be very ugly! Could someone please help me?
