Roman numeral indicators for fret positions have been requested before, but I am creating a new post as I would like to share some ideas. I understand that the development team, and not the user, decides how features are implemented, but hopefully this post is at least interesting to the discussion of how this feature would function.
The main issue is determining where these indicators appear, and what fret should be indicated. As Daniel has stated, a lot of those decisions are editorial, so it is unreasonable to expect Dorico to automate everything. The user has to provide some input.
Determining where to show the numeral—two options come to mind:
- Similar to playing techniques, a selection is made and the numeral is added at the start of the selection.
- Similar to harp pedalling, the numerals are in effect throughout, with a layout option to show/hide them across the layout, and a properties panel switch to hide them individually. The user could then add fret position markers where necessary.
Determining what numeral to show:
As a guitarist, I cannot think of a situation where the index finger is not playing the lowest fret in a given position. Thus, the Roman numeral could be determined by identifying the lowest fret number (excluding 0) within the relevant section of music. For the playing technique approach, this would be the lowest fret number within the selection. For the harp pedalling approach, this would be until the next Roman numeral (or end of flow).
The numerals would be entirely dependent on having the desired fingering on the tab staff, but that shouldn’t create too many problems because you already have the positions chosen if you are using the Roman numerals.
Currently, Dorico places notes as close to the nut as possible. It would also be nice to have the Roman numerals affect the tab. This would function as Dorico placing notes as close to but not lower than the Roman numeral. Essentially, treating the fret marked by the Roman numeral as the nut, and running the same process as it does currently.
Just throwing out some ideas and obviously don’t expect anything in the next update(s). Been really enjoying working with the guitar features added since 3.0!
