Re: "Long" Notes
They [breves] are just like any other note!
If this is true, then this discussion is moot. Simply use one of those other notes in place of the breve!
But there are other issues:
- how does a breve/longa align with other notes in a split chord?
- how does it align with itself?
- where do the augmentation dots go?
- where should a slur start or end
- where should a tie start or end
- when justifing, how much horiontal space should a breve/longa occupy?
- how do augmentation dots affect justification and slur/tie positioning?
- how do all of the above change for an an interval of a second?
If there are definite answers for the above for all these formats, a general solution might be in reach.
