> OK, I got my build working (except for an occasional crash like David
> Bolton-2 was getting:
> http://dev-list.musescore.org/Windows-compilation-error-td7577671.html )
> and I'd like some guidance on a new feature that I'd like to implement.
>
> The idea is to add guide lines to each staff and appropriate ledger lines
> that show the positions in the scale that have half steps, as an aid for
> singers sight reading music. Here is a mock up made by hacking
> StaffLines::draw
>
>
> The red line is just below the tonic of the scale and the blue lines are
> between the 3rd and 4th.
>
> The interval between the first two notes is a major second since there are
> no guide lines between them; same for the third and fourth notes. The
> interval between the second and third notes is a perfect fourth since there
> is one guide line between them; same for the fourth and fifth notes. The
> interval between the last two notes is a minor third since there is a guide
> line between them. By looking at the number of guide lines between the two
> notes and any accidentals, you can quickly determine the quality of the
> interval.
>
> The guides can also be used as a help for solfege, since the tonic, "do,"
> sits on the red line, and they can be used to help determine the quality of
> chords.
>
> Now for the programming details:
>
> I think this would fit in on the View menu as "Show Interval Guides" along
> with the other "Show..." items, but I'll be happy to put it wherever you
> think it fits best.
>
> This would only apply to STANDARD_STAFF_TYPE, not percussion or
> tablature. The physical position depends on the clef and the key. There
> are a few things I am not sure of, though:
> It could be part of StaffLines and LedgerLine or it could be a new class
> derived from Element or two classes, one for the staff guides and one for
> the ledger line guides. If it uses new Element's, then should they be
> deleted when the "Show Interval Guides" is switched off or should they be
> just made invisible? Should there be an instance every time the key or
> clef changes in a system, or should there be one element per score that
> interprets the staves, clefs and keys? If it uses existing Element's,
> should the setting be saved with the score file (like "Show Frames") or
> just be a display option?
>
> Any advice would be welcome.
