I need better glissando notation for harp music. There is this technique called a “double (or 2-hand) glissando”. In the (technically difficult) case when two or more notes are glissed in the same direction while maintaining the interval, it’s easy to create multiple lines between the multiple notes. However, the technique can also refer to a much simpler technique whereby the two hands alternate in the same direction creating a “swooping” effect. I believe that’s also called a double-glissando but even harpists I’ve asked aren’t very helpful (if anyone knows a more specific term, please let me know!). The ability to change text on a glissando would solve this problem and many others.
There may be a notation with three staggered parallel lines over the gliss that indicates the latter type of double glissando. I accomplished that by creating three lines in a graphics program, iterating to find the correct angle, and then putting the lines in an image frame. This is not a good solution because any change whatsoever (like adding pages, or moving a song in a book, or the measure changing length) requires special treatment.
Love Dorico, regardless!
